I'm doing a CA 540X to fix an omitted 2010 to 2011 tax loss carryover. I've updated Turbotax and have the amended 540 which will increase my refund substantially.

On the 540X, lines 2, a thru d for CA adjustments, the instructions say:

"On line 2a through line 2e, show adjustments to your federal AGI as negative or positive amounts based on differences between California and federal law."

I don't get how to determine if positive or negative.

On the original 540, there are 2 adjustment numbers: subtractions and additions. the subtractions happen to exactly equal my SS benefit. The original addition was a much bigger number, the amended number is $5. However I do it, I don't see the 540X numbers matching those on either the original 540 or the amended one.

Any suggestions?

Thanks.
