"Step 2: Form 1040-X
Beginning with the 2019 tax years, amended federal returns are able to be electronically filed as long as you electronically filed the original return. 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 at the IRS website."
