If you received a tax form with income in 2021 that was not reported on the 2021 tax return that you filed then you will have to amend the tax return to add the income.
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 16 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.
The federal amended tax return, Form 1040-X, for tax year 2021 is estimated to be available in TurboTax on 03/17/2022
