If she qualifies as a dependent on your return, you are entitled to any tuition benefits (credits or deductions) on your return, so you should add the 1098T to your return.

You will need to amend her return if she received any benefit (credit or deduction) from having the tuition reported on her return.  If you used TurboTax  to prepare her return, the easiest way to determine that would be to start the Amend process on her return and delete that 1098T.  If it doesn't change anything, you don't need to finish the amendment.  If it does, you will need to finish the amendment.
