Tuition and Fees Deductions from 2018 to 2019.

I am doing a check.  I was doing my 2019 taxes and I got the to the 1099-t education form. Basically not much has changed from last year to this year on the form except ~+$100. When I am doing with my 2019 taxes this year I qualify for "Tuition and Fees deduction" this year but in 2018 I did not. What has changed?
