Why is TurboTax Amend locking in $0 for Tuition and enrollment fees but not books/material, when the tuition fees is the portion I need to amend?

Attempting to Amend 2019 filing to enter my 1098-T information. I can alter the books/materials purchased from school but I cannot edit Tuition and Enrollment fees. It is set at $0 with no edit box like the other areas.
