In California what forms do i need to send in when i file for my refund by mail

 The 540 form.  If you're using TurboTax and you go to download the state, it will ask you which state and download what you need.

You should print the entire return and all Schedules to mail with the main tax form (CA Form 540). Attach any tax form showing income tax withheld such as your W-2 form. Below is the mailing address for returns with a refund or no balance due:
