Education credits / scholarships

My son did a paid summer internship (chemistry) at the University of Iowa. That is not his regular school. He attends Wheaton College in Massachusetts. They send me a 1098-T each year, which I am accustomed to dealing with. The University of Iowa did not send a 1098-T, but I have a "substitute". According to this, his stipend (?), or payment for his paid internship has been considered a scholarship  (Box 5 on a 1098-T). I'm unsure of how to claim this. Oh, we claim him as a dependent. Can anyone help?
