There's a simple way to do it. Enter in the educational expenses and scholarships section. When asked to enter his 1098-T, enter it with box 1 blank and the taxable amount, previously calculated (on your return) in box 5.
That amount should appear on line 8r of Schedule 1.
That assumes, you agree with TT's calculation. If you're not sure, provide some numbers and I'll review them.
Scholarships are a hybrid between earned and unearned income. It is earned income for purposes of the $13,850 filing requirement and the dependent standard deduction calculation (earned income + $400). It is not earned income for the kiddie tax and other purposes (e.g. EIC). So, this means if that is his only income, he does not need to file if it's less than $13,850. But, you may want file anyway, to document the reporting of the income, that allows you to claim the credit, on your return.
