New Tax law on Taxable scholarships

So if the taxable scholarship plus wages is greater than the standard deduction, how are taxes calculated? Say $10k taxable scholarship, $8k in wages, which would leave $6k of taxable income - but how much is considered earned, and how much unearned? (For FY2018, which I think uses rate tables for trust and estates per this thread?)

ETA: I just realized that my summer income is a “stipend” - would that be taxed as earned or as unearned? It is NOT earmarked for anything specifically (food, travel, conferences, education)… And I was required to work an average of 40 hours per week to maintain the “stipend.”
