Per their 2017 Form 540 Instructions -
"Itemized deductions.
Figure your California itemized deductions by completing Schedule CA (540), Part II, line 38 through line 44. Enter the result on Form 540, line 18.
If you did not itemize deductions on your federal income tax return but will itemize deductions for your Form 540, first complete federal Schedule A (Form 1040), Itemized Deductions. Then complete Schedule CA (540), Part II, line 38 through line 44. Attach both the federal Schedule A (Form 1040) and California Schedule CA (540) to the back of your tax return."
