where do i input for the senior tax credit

[CatinaT1]

The deduction is automatically calculated by TurboTax if you qualify. The calculation will appear on Schedule 1-A page 2, Part V Enhanced Deduction for Seniors, which is then carried to your Form 1040 line 13b. 

The maximum deduction is $6,000 for each person 65. There is a phaseout of the deduction once your income (MAGI) exceeds $75,000 for single or $150,000 for married filing jointly (MFJ). On a joint return the phaseout is calculated separately for each person.

On a joint return the phaseout is calculated separately for each person, so the 6% phases out for each spouse. This deduction is intended to provide tax relief for seniors and is in addition to the existing Standard Deduction or your Itemized Deductions. Expires December 31, 2028.
