Go through the entire education interview until you reach a screen titled "Your Education Expenses Summary". Click edit next to the student's name. That should take you to a screen “Here’s your Education Summary”. Click edit next to the section you want to change; probably, Scholarships/Grants in your case. Be sure you didn't enter the $6150 again there. It only needs to be entered once (at the 1098-T screen).
To edit the 1098-T, click edit under Tuition/(School name) at the “Here’s your Education Summary” screen.
Worst case: At the "Your Education Expenses Summary". Click Delete next to the student's name and start over.
