What does this question mean: "Did you provide over half of your own support with earned income during 2018?"

Earned income can only be reported on two documents, and that's it. One is a W-2 for income that you earned working for an employer at a job. The other is a 1099-MISC with the income reported in box 7 of that form which you earned through self-employment.

It's also possible that if you were self-employed that not all of that self-employment income was reported on "any" tax reporting document. But you are still required to report the income on SCH C.

So did "YOU" earn enough income from working in 2018, to have provided more than half of your own support for the entire tax year?

My guess is that you are an undergraduate college student, and it's highly, highly doubtful that you provided more than half of your own support.
