Question

I just noticed that the numbers on line 1 (wages) are more than what I made. I don't know why.

It says SCH 1584. What is that?

SCH by 1040 line 7 Wages is taxable scholarship income.

Taxable scholarship is any grant or scholarship amount that exceeds qualified educational expenses (tuition, fees and for undergrads, course materials[books]). Loans are not scholarships and are never taxable
