Get your taxes done using TurboTax

Under Forms it is the Student Information Worksheet, the Questions on that form , specifically how many years has the American Opportunity Tax Credit been taken. I can't seem to navigate to that section in the Step-by-Step now that I have answered those questions, I can't go back? I have tried going back and forth, but this is an example of why the Walkthrough of Turbo Tax is frustrating.  I need to modify / update what was originally entered. This has happened in past years, can't go back, and find something.  I debated not getting Turbo Tax this year, specifically due to the poor navigation. I always feel like I am missing something. I guess I can update the Form itself, but would rather use Step-by-Step.
