I'm not sure how it got reported twice, but we can try to find out.
If it has. Select one and click on the trash can that is on the right. It will ask Are you sure you want to delete this 1099-R?
Answer Yes.
Do you have more than one 1099R? What was the RMD from? Your IRA or a 401K? Since the RMD was waived for 2020 did you put it back or roll it over to another account or from a 401K to a IRA?
Delete the 1099R and re enter it. That may clear something out. If it was from a IRA see if the little IRA box between boxes 7&8 is checked on your form and on the screen.
