I have a query about my taxes.

A little brief about me. I am an international student working on F1 visa currently on my OPT Stem extension in CALIFORNIA. I am a 1099 Independent contractor.

1. Do I have to pay State tax in CA given my above explained scenario ?
(I had gone to a tax consultant who told me that I have to FILE State tax forms but Don't have to PAY State tax in CA because I am on F1 Visa with 1099 contract)?

2. What federal & State tax forms should I fill ?

Please advise.. thanks for your time
