Why does my standard deduction not go up when I added a dependant? is the calculator broken?

Your standard deduction is based on your filing status, not on how many dependents you have.

2021 STANDARD DEDUCTION AMOUNTS

SINGLE $12,550  (65 or older + $1700)

MARRIED FILING SEPARATELY $12,550  (65 or older + $1350)

MARRIED FILING JOINTLY $25,100  (65 or older + $1350 per spouse)

HEAD OF HOUSEHOLD  $18,800  (65 or older +$1700)

Legally Blind + $1350

That being said----did you file as Single----are you actually Head of Household?

Am I Head of Household?

If you qualify as Head of Household, when you enter your marital status (single or married filing separately) into MyInfo, and then enter your qualifying dependent, TurboTax will offer HOH as your filing status.

You will get the credit for dependents on line 19 or line 28.  The Standard Deduction has never included dependents.  You used to get the personal exemptions for everyone but that went away and the Standard Deduction was increased.
