Im just reading the top of the form that says
"State Required Information
The California Franchise Tax Board requires the following information to be presented to all taxpayers:"
(or are you referring to something else?)
So I'm guessing that the FTB has required Intuit to add this to the client copy for all CA returns.
If you are choosing to not present it to your clients, you can make it not print in the Print Options > Control Which Form Print and mark it to Never.
Under "Options" (but for unknown reasons, NOT under "Master Options"), on the "Items to Print" tab. Select Client copy on the left then navigate to "General" in the Print Order pane. There is a checkbox for "Agency Disclosure Statements" you can uncheck. I did this for a PA client but I assume it should be the same for CA.
