It depends on where you live. Most states require taxpayers to paper file amended returns.
TurboTax supports e-filing your amended return in the following states:
- North Carolina
- New York
You can e-file an amended return in the following states, but not in TurboTax. If you're amending in one of these states, you'll need to print and mail your return or e-file directly with your state.
- District of Columbia
- New Jersey
- New Mexico
- South Carolina
- West Virginia
Note: For amendments prior to tax year 2020, you must mail a paper return. While your state may accept e-filed amended returns, TurboTax may still have you mail a paper return. This includes amended California returns.
