Can I receive credit, an exemption, for being legally blind; I have in the past?

The question about being legally blind is in My Info.  Go through those screens to click on "legally blind."

You get an amount added to your standard deduction.

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.

2023 STANDARD DEDUCTION AMOUNTS

SINGLE $13,850  (65 or older/legally blind + $1850)

MARRIED FILING SEPARATELY $13,850  (65 or older/legally blind + $1500)

MARRIED FILING JOINTLY $27,700  (65+/legally blind) )  + $1500 per spouse
