megan24,
I did my CA tax return on paper, putting the $300 in column B as instructed, and got a bill for additional tax. Turns out it is a CA Franchise Tax Board error. They ignored the federal AGI on Form 540 line 13 and substituted Form 540 line 23A instead. This resulted in adding the $300 in twice, once by including it in line 23A and a second time by subtracting it from line 23B. I am formally protesting this double addback. I suspect it won't get straightened out for months. Last time they made a mistake, I had to go through the Taxpayer Advocate's office to get my missing refund.
