just so we are on the same page, you input the 1098T form EXACTLY as it is printed. there is $1120 in Box 1 and $75 in Box 5.
I think there must be a question that wasn't answered because it's seeing the $75 as income and not giving you the AOTC credit.
If you are using desktop (I don't know how the online version works), go into Form view and look at the line where you spouse is info is listed and the indented line below that. Review the answers to all the questions. I think you will find an unanswered question somewhere.
looks like there is a good chance your joint income is above $180,000.... if so, I wouldn't even worry about entering the form; it gets you no value as you are not eligible for AOTC.
let me know.
