Just enter the 1099R you got exactly as shown.
Since there is no RMD required for 2020, after you enter the 1099R say it was NOT an RMD and then that you rolled it over (even if back into the same account). You will get credit for the withholding taken out on 1040 line 25b.
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.
