You can change your taxes if you haven't actually mailed them by following these steps:
- Login to your TurboTax Account
- Scroll down to the bottom of your page and click on the blue box "Add a State" (You are not actually adding a state but this gets you to the correct menu)
- From here, you can click "Federal" from the left side of your screen and then change what you need to change
- Walk through the "File" section to reprint or E-File after you have made the necessary changes
