I am all the way done with data entry and have printed returns, but I want to review all inputs because i have several changes to make. How do i do that.

Use "add a state" to get back in your return to make corrections (before filing).

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.
