How can I edit my federal return. I have paid, and viewed to print, I need to uncheck one box?

If you haven't filed your return and see the Tax Home screen "Ready to mail" when logging into TurboTax then please follow these instructions:

1. In TurboTax Online, sign into your account.
2. Select Tax Home in the left menu.
3. Scroll down to Your tax returns & documents.
4. Select 2018, and then select Add a State (you're not actually adding a state, this opens the return back up)
5. Make changes
