You appear to be asking about 2020, rather than 2019. It appears that the answer will depend on the support rule. The IRS has a worksheet that can be used to help with the support calculation. See: http://apps.irs.gov/app/vita/content/globalmedia/teacher/worksheet_for_determining_support_4012.pdf
Bur if makes more than $4200, you can't claim him, if he is not a full time student. See full rules above
