Scholarships and unearned income

My son's scholarships exceed his educational expenses. It is my understanding that the excess would be considered unearned income and would be subject to the kiddie tax. But for some reason, TurboTax is not classifying it as unearned income and Form 8615 is not being generated. I filled out the 1098T. Why is the amount not being classified correctly? It shows up on the Wages, Salaries and Tips Worksheet as "Scholarship/fellowship income" as it should. But it does not automatically transfer over to unearned income as it should. All guidance I find online says that it should be classified as unearned income and should be subject to the kiddie tax. What am I doing wrong?
