I have exactly the same problem, plus when I look at the .pdf of my tax return I realized that TurboTax is using the year 2020 version of the form. Spent 4 hours on the phone with TurboTax, couldn't even get a case number. Unfortunately, TurboTax has chosen to hide all the forms, so one cannot manually correct the entry. TurboTax suggests I file a paper return, but the return will still have the incorrect information in it.
