I did some more investigation on this. I thought maybe TT saw that my spouse turned 70.5 last year on Jan 2, 2022, so maybe the dis-allowance of the deduction wouldn't begin for my spouse until the following tax year. To test this theory I changed my spouse's birth date to make them 80 years old last year, and TT still only adjusted my IRA deduction and not my spouse's on Schedule CA, line 20. So there is something else going on here; it is not age related. Another theory: if one earns at least $7000 of wages after age 70.5, can you still deduct your IRA contribution for California taxes? I could not find the answer to this anywhere online.
