Yes, you have to change the amount reported in Box 2 of form 1098-T as you can only report tuition exactly paid.
In TurboTax, when
filling out your form 1098-T, enter
only the amount in Box 2, even if both boxes 1 and 2 are filled.
Under box 2, on the
1098-T screen is a link: What if this is not
what (student name) paid to the school? Click on that and you will be
given a chance to enter what was actually paid in 2016.
