Filing california tax by mail

[ABC04202020]

If I submit federal tax though efile and california state 540 by mail, do I have to attach federal tax forms?

Printed turbotax forms indicate - Do not attach federal return

However,  FTB ( https://www.ftb.ca.gov/file/ways-to-file/paper/index.html ) indicates

Attach a copy of your federal return (if not using form 540 2EZ)

Which one is true for 2020?

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.
