You do not have to file a tax return just because you got a 1098-T. The 1098-T is only an 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 are either eligible for a tuition credit or possibly the student has taxable scholarship income.
How old are you and how do you support yourself, if you are not a dependent?
If you are a student, over age 23, and are not claimed as a dependent by someone else (e.g. your parent) you may be eligible for the up to $1000 refundable American Opportunity (tuition) Credit, by "filing" your 1098-T.
