Why is my Standard Deduction under "Your tax breaks" listed as $14,700 (I am a single filer)? Not the $12,950 amount?

Are you 65 or older?  You get an extra 1750.  If not then check your birthdate under My Info.

For 2022 the standard deduction amounts are:

Single 12,950 + 1,750 or 65 and over or blind (14,700)

HOH 19,400 + 1,750 for 65 and over or blind

Joint 25,900 + 1,400 for each 65 and over or blind (28,700)

Married filing Separate 12,950 + 1,400 for 65 and over or blind
