Can I change my "Tuition and enrollment fees" from incorrectly showing as $0?

I supported myself in 2019 and was enrolled full-time. When I get to the section that *should* allow me to input my 1098-T form (as I've done easily in previous years), the amount listed for "Tuition and enrollment fees" is $0 and I'm unable to change this.

All I'm able to list is books and materials that are or aren't required to be purchased from my school, but there's nowhere that allows me to input my tuition fees. I have triple-checked that all of my previous information is correct, so I have nowhere else to go with this question.
