As long as you haven't filed .You can get back in to make corrections .(you just have to trick it a little) If you have already filed you would need to file amended returns.
To access your State tax return to make corrections after printing, but before mailing your return, you can "add a state" to make changes:
Please try this:
Sign In to Turbo Tax Online
Click "My Turbo Tax" menu.
Press "Visit My Tax Timeline"
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).
Click"Federal"tab then press "Edit" to make changes.
