Son is a college freshman, so this part is new. I entered something incorrectly, and when I went back to fix it... How do i restart the section?

To get back to the Education section, look for that topic under 'Deductions & Credits' or type 'Education' in the Search area.

 

You will enter info about the Student, about the School, and then enter either a 1098-T, and/or amounts for Qualified Education Expenses.

 

Basically, you may qualify for Education Credits for amounts you paid 'out of pocket'  for yourself or your dependents education expenses.
