My notes say....(they might be old since there are new federal schedules 1-3 now)
540 Instructions page 20 say
Other than Schedule A (Form 1040) or Schedule B (Form 1040), did you attach any federal forms or schedules to your federal Form 1040?
If No, do not attach a copy of your federal Form 1040 return to Form 540.
If Yes, attach a copy of your federal Form 1040 return and all supporting federal forms and schedules to Form 540.
Exception: If you did not itemize deductions on your federal tax return but will itemize deductions on your California tax return, complete and attach a copy of the federal Schedule A (Form 1040) to Form 540.
