I found this on the forum:
Because RMDs were waived for 2020, the distribution was not an RMD even if that was the original intent of the distribution. After entering the Form 1099-R exactly as received, you must indicate that none of the distribution was RMD, then indicate that you moved the money to another retirement account (or returned it to the same account), that you rolled over the distribution and that you rolled over the entire distribution. TurboTax will include the gross amount on Form 1040 line 4a or 5a but will exclude the entire amount from the taxable amount on line 4b or 5b and will include the word ROLLOVER next to the line.
I scrolled down to RMD on 1099-R and unchecked the "Entire gross is RMD and entered $0.00. That worked to remove the tax on the RMD.
