If you have NOT already filed the 2022 tax return, you can add the W-2 you received to the 2022 return.
Using TurboTax a 2022 tax return can be e-filed at any time on or before October 16, 2023.
If you have filed the 2022 tax return then you would need to amend the 2022 return that was filed to add the W-2.
An amended return, Form 1040-X, can only be printed and mailed to the IRS if the original tax return was not e-filed. The IRS will take up to 20 weeks or longer to process an amended tax return.
Before starting to amend the tax return, wait for the tax refund to be received or the taxes due to be paid and processed by the IRS.
