Dependent son's standard return had his income increased over his W2s by over $2500. Submitted before seeing line 1.SCH 2547. What is this - how do I fix?

What is schedule 2547? We claimed him as a dependent.  He has normal jobs, no investments nor do we his parents. He is college student.  Entered 1098T info and system said no tax breaks because parents claimed him.  We knew that there would be no break.  Help.
