if your turned 24 in 2019 (born in 1995) you CAN only be a dependent if the following tests are met (answer from your parent's perspective)
1.The person either (a) must be related to you or (b) must live with you all year as a member of your household. (your parents already pass this test since you are related)
2. The person's gross taxable income for the year must be less than $4,200 in 2019.
3. You must provide more than half of the person's total support for the year. (financial support means fair share of rent, food, utilities, clothing, transportation, medical costs, insurance, COLLEGE costs, etc.) if they provide more than 50% of this stuff, they pass #3)
4. The person must be a U.S. citizen, U.S. resident alien, U.S. national, or a resident of Canada or Mexico.
if they pass all 4 tests, you CAN BE a dependent and are not eligible for stimulus.
if they FAIL ANY ONE test, you CAN NOT be a dependent and ARE eligible for stimulus.
let me know whether they pass or not and I can advise on the solution.
