Why would your bank be involved with your CA state tax returns? Did you receive a notice in the mail from the California FTB?
What you are describing may be a scam so you need to verify why the FTB needs a copy of a tax return from 9 years ago.

TurboTax only keeps tax returns online for seven years so tax year 2010 would not be available.
