How to fill 1098-T if employer paid for a part of tuition, and I paid for the rest?

I was at least half-time enrolled in an educational program this year, and my employer paid for 80% of the program. I first paid for the expenses on my personal account, and upon proving to my employer that I had passed the course, my employer reimbursed me, up to ___$.

I am not sure how to acknowledge the reimbursed amount vs. the remaining amount I paid. In addition to my remaining amount, I also covered textbook fees. 

I was enrolled in the same program last year (without employer reimbursement) and qualified for a return.

Please advise, thank you.
