Do you send the federal tax return with the state tax return in California? Also, does California have the same mailing address as the IRS?

No.  The mailing address for a federal tax return and a  state tax return are completely different.

Go to this IRS website for the address to mail a federal tax return - https://www.irs.gov/filing/where-to-file-paper-tax-returns-with-or-without-a-payment

Go to this CA FTB website for where to mail a California state tax return - https://www.ftb.ca.gov/help/contact/mailing-addresses.html

If Turbo Tax printed out 2 copies of the federal (one is behind California) then CA wants a copy of federal 1040 included.  It should say where and what to mail on each coversheet instructions.
