How much the student earned is irrelevant. he can earn a million dollars and still qualify as your dependent. The student's earnings do NOT in any way, form or fashion figure into this equation.
Most likely, you answered the support question wrong by selecting YES.
The question is asking if the STUDENT provided more than 50% of THE STUDENT'S OWN SUPPORT. So if you answered that question YES, then you do not qualify to claim the student as a dependent at all.
