For 2018, box 2 is no longer an option for reporting on Form 1098-T. If you have received a Form 1098-T with box 2 amounts instead of box 1, then your school has either not filed the forms correctly or they are using an outdated system of reporting.
You should seek a corrected Form 1098-T that reports box 1 expenses paid. If you can’t get a corrected form, then select the blue link for “What if this is not what I paid to this school” on the Form 1098-T page and enter your expenses based on your school records.
You need to enter at least $1 in box 1 (you cannot leave it blank) and you can then use the blue hyperlink to override the amount. That amount then gets used on Form 8863 for the Tuition credit calculation.
