I was having the same exact issues for weeks. I found a reference to go to the IRS site and login. I had to create an account and when I used the numbers that were on the site it worked perfectly. I put in just what i paid for Fed and not the total amount. Example - I paid $2k for federal and got back $500 from state. Turbo tax shows $1,500 total 2019 tax due, however the number they want to know is Federal. That got me through the next screen... FINALLY! Hopefully this helps some others.
