After you file

If you have already paid, follow the steps below.

How do I go back in and make changes after paying.

1. Sign In to TurboTax Online.
2. Click "My TurboTax" menu.
3. Press "Visit My Tax Timeline"
4. Under the "SOME THINGS YOU CAN DO" heading, choose "Add a state" (you're not really adding a state, this allows you to get back into your return).
5. Complete/correct as needed.
