If your return has not been filed, you do not need to file an amended income tax return.
If you need to make changes to your return prior to filing
your Income Tax Return, the only way to get back into the return is to follow
the instructions below. You are not
really adding a state, you are just telling the program that you want to so
that you can open the return and make the corrections you really need to make.
- Log in to your TurboTax Online Account
- From the Overview page Click on My TurboTax
- My Tax Timeline
- In the Some things you can do area Select Add a state
This will let you
back into your Return to make corrections and file it.
