Did the State of CA tell you this? Are they requiring you to Amend your return? A lot of times, if they send you a letter about this, you don't have to amend, you just need to agree with their changes.
If you need to amend, there is a FAQ below. I would send a copy of the Federal return with the Amendment. It probably isn't needed, but just to not cause any delay.
See this TurboTax FAQ for help with amending.
