Im a F1 student studying in California frm 2023. I earned in the state of Washington in summer 2024. Do I have to pay California state income tax on my Washington salary?

If you are a non resident for US Tax Purposes, you would need to file a 1040NR, this means any state returns you file would be filed when you file that form.  TurboTax does not support the 1040NR, but our partner Sprintax does and can help with your non resident return for state and federal questions.
