Completed stat return, but now learned total state wages listed box 16 of 2022 W2 is incorrect. I have been told to file form IT-225 w/ my tax return. How do I fix this?

TurboTax adds form IT-225 to your return automatically if you have adjustments to make between your federal and New York returns.  When you're entering data into your New York return answer all of the questions carefully.  If there are any adjustments let the program know.  The form will get added.

The software adds this form automatically as needed. TurboTax uses an interview format so that you don't need to update the forms. This form isn't filed separately; only with your state tax form.  The state starts with a subtotal from your federal return and then allows for additions and subtractions for the state tax. This is a form for reporting additions and subtractions that aren't otherwise listed on the main NY state return.

you should really request a corrected W-2 from your employer.

File an amended New York return if you've already filed your taxes. As Tax Champ Mike9241 said, it’s better if you get a corrected W-2 from your employer.

Either way, TurboTax does support Form IT-225. You did not say whether you are adjusting your wages up or down and whether you are filing a resident, part-year resident, or non-resident return, or whether you are using TurboTax Online or CD/Download. We'd have to know about those things to help with IT-225.

It’s likely you will have to use CD/Download if you use IT-225 for a wage adjustment. That's not a common situation.
