Make sure your original 2019 return was fully processed before you amend. If you were due a refund, wait until you receive it. If you made a payment due, wait until it has been processed.

To amend your return:

  1. Sign in to TurboTax.
  2. Scroll down to under Your tax returns & documents, select Amend (change) 2019 return, then Start amending my 2019 return.
  3. Then, select the reason you’re amending and follow the onscreen instructions.
  4. When you’re done, we'll give you instructions for printing and mailing your amended return, since amendments can't be e-filed.
