Retirement tax questions

Turbo tax does not handle someone who was 70.5 in 2020 and not 72. My work around was to change my age:

From 1949

To       1948 and then I could enter the QCD information. It looks like a calendar arithmetic error. 

If you are 72 and do a QCD the software will work. Per page 25 of the 1040 instructions if you are 70.5 when you did a QCD it is tax free. I was 70.5 in Jan of 2020 so the software did not work for me unless I changed my birth year from 1949 to 1948.
