Where can I see a breakdown of how my SALT deduction in Schedule A is calculated in TurboTax Online version?

[lht2134]

The numbers on the Schedule A for my SALT deduction for state and local income taxes do not match the numbers on my W-2. How can I find out where the numbers are being pulled from?

TurboTax will also pull numbers from other sources, including state taxes from 1099s, prior year state balances, estimated state tax payments and extension payments made during the 2025 calendar year.

To see exactly how these numbers are being calculated, you can review the State and Local Income Tax Worksheet.

Since you are using the TurboTax Online version, you will need to finalize payment prior to viewing the forms.

To print and save all forms:

1. Go to Tax Tools on the left hand panel inside of TurboTax
2. Click on the down arrow and scroll down to Print center
3. Click on Print Center and select Print, save or preview this year's return
4. If you have not yet paid, you will be guided through the payment process first
5. Keep in mind that for 2025, the total deduction for state and local taxes (SALT) is capped at $40,000. If your total payments exceed that amount, Schedule A will only show the capped limit

Schedule A is any state and local payments you actually paid in 2025.  Here’s a list of most things it can be…….

A Jan 2025 payment for the 4th qtr 2024 tax return 

A 2024 state extension payment made in 2025

A 2024 or prior state tax due paid in 2025 like on your 2024 tax return

A  2024 state refund you applied to 2025 is an estimated state payment

Any 2025 state estimates paid Jan 1 - Dec 31, 2025

Any state withholding from your paychecks, retirement checks

Any local taxes withheld like SDI in box 14 or 19 on your W2

But not a 4th qtr 2025 state estimated payment made in January 2026.  That goes on next year's 2026 federal schedule A.
