OK, so I spent an hour on the phone with TurboTax help last night, and finally figured it out. If you enter in your W-2 information, and then stop, and go directly to Federal Review on the left hand side, then go ALL the way through the review process (bypass anything that tells you it requires your attention), at the end it will FINALLY show up. Then, it will stay there, and you can go back and enter all your information in, and it will calculate for you as it has in prior years.
They really need to fix this for years going forward, but at least it's not gone altogether.
Hopefully this helps others, because it was really frustrating trying to figure it out.
