You need to enter the correct info on the RMD screens. If you took money out as a required minimum distribution then roll it back into the IRA under the Cares, in the RMD screens in TurboTax you should enter "None of this withdrawal was RMD". That will take you to the "Tell us what you did with the Money". There you can indicate you rolled all or some back into your IRA.
If you don't see the RMD screens, make sure and check your age in the My Info section to insure you are 70 1/2.
