I read on the IRS website that I may not even receive a form if my tuition was completely covered with grants, scholarships, third-party etc.
The issue becomes how much income is taxable to you. If you are given scholarships, grants, etc in excess of your school expenses, that difference is taxable income to you.
You need to report the taxable income. Having the 1098T allows you to think through your options. Go online to your school Bursar account and look for your tax document. Most schools post it online.
I am also going to recommend you look at another of my answers for help. You need to start gathering your various expenses.
Simple answer: No. 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 deduction or possibly you have taxable scholarship income.
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)
You claim the tuition credit, or report scholarship income, based on your own financial records, not the 1098-T. Scholarship income, if any, must be reported.
