Deducting Educational payments back to the employer

Hello, My employer paid for my tuition for graduate school for years 2015 and 2016. There was an agreement to stay at the company for 2 years after tuition has been paid. If I left early, I would have to pay back the tuition paid by the employer to the School within last 2 years. I quit early and now I am paying back the tuition cost paid in last two years as monthly payments back to the employer. Is there a way to claim these payments as educational expenses? How else can I deduct them on the 2017 tax return?
