How do I know if I filed in 2021 with standard deduction or itemized deductions?

I’m using my 1040-SR line 20a the amount that shows is 27,800 is this showing that I used standard deduction or itemized?

27,800 was the 2021 Standard Deduction for a Joint return with both spouses over 65.  And you meant on 1040SR line 12a (not 20a).
