What tax year? What is your filing status? What do you see on line 12 of your 2020 Form 1040? Did you double check the dates of birth you entered in My Info? Remember it goes by your age at the end of 2020 for a 2020 tax return. (If you are working on a 2019 tax return, then you had to be 65 at the end of 2019.)
