None of the replies I have received address my issue.
I began receiving my RMD at 70.5 years. I have used Turbo Tax for at least 20 years with no problems. BUT 2 things happened that set me up for problems. There was no required RMD for 2020. Note that until then my non-taxable portion had been properly calculated by Turbo Tax. 2nd thing, my computer died and had to be replaced. I inserted my CD from 2020 and Turbo Tax recognized all my info and loaded it. Please keep in mind that my 2020 file did not have any RMD info at all. I have manually calculated the info for 2021 Form 8606 to determine the basis for the tax exempt portion of my RMD. in the input screen for RMDs I entered the total RMD from T. Rowe Price and entered the taxable amount in the box immediately below it. Turbo Tax does not recognize that info and therefore does no create a Form 8606.
I have CDs of my Turbo Tax created returns for several years.
