Multiple states and tax filing
My student son goes to school in Philadelphia and works part time and pays local Pennsylvania taxes, and he also interned in NYC and got a significant NY state tax withheld. Since he is being claimed as a dependent by his parents and being a student living outside CA, Turbo tax is asking him to file CA taxes and pay taxes in CA as a resident when he has earned nothing from working in CA. How should we handle this situation? Thank you
