If you were 65 or older at the end of 2023 it is added automatically to line 12 of your Form 1040.
Your standard deduction lowers your taxable income. The standard deduction makes some of your income “tax free.” It is not a refund. You will see your standard or itemized deduction amount on line 12 of your 2023 Form 1040.

For joint filers where one spouse is 65 or older the amount would be $29,550 and where both are 65 or older $31,400.
