I need dog training advice, please.

Moving is stressful, she just hasn't quite figured out what is expected of her. Is she alone a lot?

Crate if you aren't watching her. The key is not having a chance for her to make a mistake. Try not to have her crated for too many hours though.
Take her poop from accidents and put it outside in the area where you want her to go.
Take her out without the other dogs but if she doesn't poop in a reasonable time, bring her back in. Try again a bit later but watch with an eagle eye.
Give major tasty, wonderful, delightful treats for pooping outside and praise her. Say Go Poop! when you see her making motions to poop.
Say Go Pee! when she is about to pee. Treats immediately after the pee. Praise alone is not enough.
Try to get an idea of when she is pooping, that is, how long after eating. So, you can anticipate best when she needs to go out.
Take her out frequently and reduce frequency as she learns to go outside again.
No punishment for inside poops. No yelling at all for accidents, just quickly usher her outside.
As someone mentioned, try not to let her see you clean it up. Be sure to use an enzyme cleaner to remove all traces of odor.

She is not alone really at all because we have two other dogs and a cat and they are all together (Sara is in her crate but it's in the living room with everyone else). And my husband is now working from home again (we finally got internet last night!!).

I can't do the one hint you mentioned above because we live in a condo and I'm supposed to pick up the poo...not leave it out there! There is absolutely zero way of keeping her from seeing me pick it up, too. With three dogs on leashes, it's just not possible to hide anything I am doing!

Thanks so much all. You guys are such a help! I need to get more treats, but we will definitely do the treat after going outside thing. Of course, then the other dogs will want them too but we'll figure it out. It'll definitely work if I'm out with Sara alone, of course.

The good news is that last night, she pooped for me!! The bad news is that she hasn't yet done it for my husband, so we'll have to work on that...

We mean pick up the poo in the house - don't let her see you clean up after her and therefor think it's "OK". Outside, on leash - in front of her is fine.

Is pup any better at going potty?

I have to walk a number of pups (adults) at once. I have found the Cesar Milan pack walk seems to help.
I keep them on a short leash (one foot-Halti) at my side or behind. We are going on a hunt--I am the leader--smells could be detrimental to the hunt kind of thing.

We start off on short leash. Walk 20 feet. Then I stop, say ok Potty, and give them their 6 foot leash. Then gather up leashes and walk command. At about 6 houses/block I stop, say ok-potty and give them their leashes. They usually get their business done. I gather leashes short again and we are off for a non-stop walk/hunt.
After the "hunt" I stop, ok-potty command and give full leash once or twice near home.

Good luck

Some really good ideas. Here is my take (without actually seeing your dog.)

As others have said, moving is stressful. It sounds like your baby is sensitive and really not mature yet. Give time time.

Crating is the gold standard for these things. Is the crate in your bedroom? That might help. For now, I'd feed her in the crate at night. After dark, put treats in the crate & give her your "go to crate" command. In short, make it a safe place at night. If you get up during the night, put a few treats in the crate & send her to it. After you feel like she's "got it", try to crate all night. NEVER let her out if she's raising a racket. (My only concern here is if your neighbors complain about the night racket.)

Last (and this is a bit gross) you can take a match (paper, not stick) & insert it slightly into the rectum to get the poop action going. People who show dogs in obedience do it because if they poo in the ring, it's an automatic disqualification. Bring rubber gloves.

Finally can you put a little piece of poo in your rock yard? It doesn't need to be big (or detectable by the condo HMO police.)

Ah...no, she still hasn't figured it out. I walked her for over an hour last night (round and round the same little spot) and while she did pee (yay!) there was no pooping going on. It's so frustrating. In fact, just this morning my husband commented on how she farts a lot and all I could think was that it's because she is holding in her poo so much. She has had zero issues with eating (or with poo consistency...thankfully), so I don't think it's an illness. I think she just hasn't figured it out yet.

Night racket won't be a problem for the neighbors...just us. We have no neighbors yet. On one side is the model home and the other side is still empty (though it is 'sold' so we'd better hurry and get this resolved!). I was thinking of the crate in the room, too....but then she flips out if she thinks we've crated her when we leave the house and she doesn't see us actually leave. This is why we moved it into the living room. Would two crates be a bad idea? We have two since the other two dogs were crated when they were young, so we could put one in each location (using the same bed/pad)...

We have gotten the actually walking part down really well. Two dogs are on pronged collars (one because she has a pin head and slips out of her regular collar and one because she pulls) and one is on a regular leash. Charlie (who has dominance issues) walks behind me to my left. Sara and Maggie (who are huge pushovers in all situations), walk in front of me on a shortened leash so that it doesn't tangle. When it's potty time, they get tangled sometimes as I give them full leash length, but the walking part is going VERY well. Thankfully, they've figured that part out.

Dogmama - I could put poo in the rock yard. Maybe I move her poo out there and then take her out there on the leash? I don't really want them to be pooping out there, but if it's a way to convince her to go on the leash, then maybe it's a good way to start?

Two crates are fine. The idea is that dogs won't mess up their den.

I think putting the poo in the rock yard & taking her out is a good idea. It might help her connect the dots.

If you don't feed twice a day, I would start. Make the morning meal larger so it has time to process through.

I actually like prong collars a lot more than slip collars, btw. Can't strangle themselves on prongs. Much less trachea injury too.

I show my Italian Greyhound, I do performance events with her and my 2 mutts and I have never seen or heard of anything like this. In the circles I know of, this would never ever been done/suggested. You could damage your dog's rectum, and the likelihood of it fully working is dubious.
I am off at dog shows about 2 weekends/month - so been to lots of shows/trials...
(almost every trial I've ever been to, at least one dog poos in the ring - it is an NQ and talked about, but not the end of the world and not a DQ - which is much much worse)

It is done quite gently with the paper end - and only inserted about 1/2 inch. It works by stimulating peristalsis.
