Tuition Reimbursement

I I was hoping someone can help me. I tried calling the IRS and they were no help. I received approx 9,500 in tuition reimbursement in 2018 and 2019. I left the job so I have to pay the tuition back. Since I am paying it back this year do I do an amended return next year for 2019 or do I take the education credit next year? Also, what is the max I can deduct each year?
