She claimed my 2016 1098-T, but she didn't have to claim the full amount to get the credit. I had $10,000 in tuition expense on the 2016 1098-T, but $5M of that was for my 2017 semester. If I use that $5M for 2017, I'll get the full benefit of the credit. Her 2016 form 8863 only claims the max amount of $4,000.
