If you believe the Form 1098-T does not reflect the corrected tuition amount you paid out of pocket, you can make adjustment in the Form 1098-T box 2.
Enter Form 1098-T in TurboTax program exactly as it appears on your form, then click on the link in blue that says "what if this is not what I paid to this school?" (below box 2) to enter the full amount of tuition you actually paid. See the attached screenshots below.
