Refund or Tax Due Amount Changing In Top of Screen
Any changes you make to your return after filing will continue to update the refund or tax due amounts (Federal and/or State) displayed at the top of the screen.
To ensure you know exactly what those amounts were when you filed, make sure to print a hard copy of your return and file it in a safe place.
Any changes you make to your return after you file are not transmitted to the IRS or state unless you file an amended return.
