Do I need to add 1098T

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 are either eligible for a tuition credit or deduction or possibly your student has taxable scholarship income. 

If you claim the tuition credit, you do need to report that you got one (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. 

 The education deduction/credit goes with the student's dependency. If your parents claim you, they claim it, and the 1098-T is entered on their return.
