We are 80+ years old. We were NOT required and did not take RMDs for the year 2020. How do I get Turbo tax to accept this fact?

Assuming you have a 1099-R, perhaps you mistakenly told the program it was from a qualified plan, when you should have indicated it was from a non-qualified plan? Just a wild guess here since there's no other information provided for me to work with. Might want to work back through the 1099-R section again and check that.

After you enter the 1099-R, you can indicate that an RMD was not required.  (See below)
