payment due on an amended return

Yes, you can e-file your 1040X Amended U.S. Individual Income Tax Return.

To amend your return:

1. In TurboTax, scroll down to Your tax returns & documents. Select Show and then select Amend (change) return, and then Amend using TurboTax Online. (If you don't see Your tax returns & documents, select Tax Home on the left.)
2. Select the reason you’re amending and follow the instructions
3. Add the new forms
4. TurboTax will calculate the amount due

 Form 1040X won't be finalized until March 25th, so you may want to wait until after that to prepare your amended return.

You can pay the amount due by mailing a check,  with credit card or direct debit from your bank account.
