It should not ask you.
Since there is no RMD required for 2020, after you enter the 1099R say it was NOT an RMD. Did you put it back in? then say that you rolled it over (even if back into the same account). Was any withholding taken out? If it was then did you replace the withholding with your own money? Otherwise the withholding will be a taxable distribution itself. You will get credit for the withholding taken out.
If you already entered the 1099-R as RMD and changing your answer to the RMD question doesn't work then you have to delete and renter the 1099-R form.
