If I printed my taxes for review, why can't I go back in to make changes before filing?

[TomK]

Please follow the instructions below to make changes or add to your still as unfiled return:

In TurboTax Online, sign into your account.

1. Select Tax Home in the left menu.
2. Scroll down to Your tax returns & documents.
3. Select 2018, and then select Add a State (you're not actually adding a state, this just opens the return back up)
4. Make changes and then refile (do NOT refile if you have already submitted your return… unless it was rejected to make a correction(s)) .  If you just want to check;/look at something on your return, but not change anything, then...
5. Click on Tax Home,
6. Click on Sign Out.
