Your employer put your CA SDI withholding amount in the wrong section of the W-2 - it's supposed to be in Box 14. Remove your entries for that in W-2 Boxes 18-20 and enter the $$ amount in Box 14 and select CA SDI tax from the dropdown list. It will then be handled correctly. SDI is not an income tax withholding so it does not show up in your Calif return as a credit in line 71.
