2. TurboTax should have asked you how you like to get the refund from your CA State tax return, if you did not enter any account information then you will receive a refund check by mail from CA.
3. The Federal and State return will be sent to different addresses. There should have been instructions with your printout. But you can look up the address for your federal return here: IRS mailing address. For your state return please look up the address here: CA mailing address
