MFJ couple has $200,000 AGI for 2020.  This would I think make them ineligible for a stimulus check.  They also have an adult college student under age 24 whom they could claim as a dependent.  If they claim him as a dependent, do they get a $500 child credit?  But if they don't claim him as a dependent, and the student files his own tax return, will the student qualify for a $1,400 stimulus check?  Is there any downside to taking the no dependent/student files own tax return route?  BTW, parents file California tax return.
