The 1098-T is not a controlling document. There is no requirement to report it on your tax return. You can ignore it.
But, If you actually made the payment in 2016, even though the classes didn't start until 2017, you can claim a credit on your 2016 tax return. So, if that's the case, and you are entitled to and want to claim the credit, you will have to file an amended return. You will not be able to do that until after your original return has been fully processed (you receive your refund).
