I highly recommend you seek local professional assistance with the CA return and they will probably be able to tell you what to do with the US return ... most likely you will get a foreign tax credit on the US for the taxes paid to CA.
Then when you know what you are doing you will need 2 TT programs ... one for the US and another for CA ... maybe the CA forum can help with your questions ... (all the CA screens have the red maple leaf on them to differentiate them from the US program) ...
