No, there's no need to start over or pay again to make changes before filing, but after finalizing.
To finish or make corrections, if you can no longer
make changes to your return, but before you've e-filed or mailed
your return, you can "add a state" to make
changes:
1. Sign In to TurboTax
Online
2. Click "My
TurboTax" menu
3. Press "Visit
My Tax Timeline"
4. 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).
5. Complete/correct as
needed.
