So I am a 19 year old that still lives with my parents, and iirc the stimulus checks this past year have been given as an advance on certain tax credits, and my parents aren't planning on marking me as a dependent since they "made" (inheritance got received as capital gain therefore counting as income) too much in order to gain any tax credits from it. Now even though I won't be getting marked as a dependent, I believe that I legally still have to mark that I am eligible to be marked as a dependent. Will the IRS use the potentiality on my taxes or the certainty on my parent's taxes to determine whether I get the tax credit or not?
