Beginning with the 2019 tax years, amended federal returns are able to be electronically filed. If you filed your return with TurboTax, log into your account and select the tax return that you want to amend and follow the online instructions. For paper-filing amended returns, download a copy of IRS Form 1040-X, Amended U.S. Income Tax Return. You can easily find it using the search function on the TurboTax website.
TurboTax only supports the e-filing of the current tax year federal amended tax return, 2021. All prior year federal amended tax returns have to be printed and mailed.
