Didn't receive my 1098-T

It depends. It would be best to get Form 1098-T. They are often placed in the student's portal. If the expenses for your final spring 2019 term were paid in 2018, you will not be able to claim the deduction in 2019. See 2019 IRS Publication 970 Education Expenses page 14 column 1 regarding prepaid expenses. 

However, you could amend 2018 to report the actual expenses paid.
