Thank you for this quick response! Prior to that, I found a way to enter it on the State side of things:
Go to Prepare State, Edit, click on Go Over California Again
Click through to Here's the Income That California Handles Differently
Edit the Business Profit or Loss Adjustment
Edit my business, click through to Other Adjustment,
Then add the name of the deduction and the amount as a negative number.
This method bypasses the Federal end of things, but it seemed to work just fine.
