Scholarships and grants do not count as support. This might seem like nit-picking but it is crucial in determining whether you can be claimed as a dependent. If you could—even if you were not claimed—as a dependent you must on your 2020 return state that someone can claim you and you would not get the stimulus. If, based on the worksheet below, you did provide more than half of your own support then you will get the 2 stimulus payments based on your 2020 return. 2019 is not relevant.
