State tax filing

Depending on what platform you are using, the screens may be a tad bit different, but when going through your CA state return, you should come to a screen titled Business Summary that references California differences.   On that screen, click the Edit button next to your business.   Click through until you come to a screen titled Other Adjustments.

If the California deduction is smaller than the federal deduction, enter this adjustment as a positive number. If the California deduction is larger than the federal deduction, enter the adjustment as a negative number.   @TR3532
