I was 70 1/2 in 2020 so I experienced this problem with Turbo Tax. I changed my birth date, entered the QCD, and went back and corrected my birth date. This worked until I got to Finish and File and it would not let me file electronically unless I fixed my file. I have talked to 3 different reps who said they were going to report the problem, but it is not fixed as of this past Thursday.
