Are you required to file a 1098T if you’re a college student? I already filed my taxes, but never got a chance to receive my 1098T yet.

No. The 1098-T is only any informational document. The numbers on it are not required to be entered onto your tax return. 

However receipt of a 1098-T frequently means you (or your parents, if you are their dependent) are either eligible for a tuition credit or deduction or possibly you have taxable scholarship income.  You claim the tuition credit, or report scholarship income, based on your own financial records, not the 1098-T. 

If you claim the tuition credit, you do need to report that you got one or that you qualify for an exception (the TurboTax interview will handle this)
