One more question which might be trivial. Do I have to file state's taxes for the states where companies I bought stocks from are located? Some companies' stocks I bought are from California.
No. You only have to file a nonresident state income tax return if you physically worked in another state other than your resident state.
Just because you own shares of a company that is based outside of your resident state in no way means that you have to file a state tax return for the state where the company is located.
