Turbotax 2024, interpreting wrongly the carryover capital loss for california tax return

If you have a loss on Line 10 for your California Schedule D, and line 12b has a positive number, that number represent the difference between Line 10 and Line 11. That difference is then entered on Schedule CA (540), Part I, Section A, line 7, column B.

Do you have a loss on your California Schedule D, and is it larger than the Federal loss?

If so, does your California Schedule CA show a Subtraction on Line 7 for the additional loss?

It's possible that the amount was added rather than subtracted depending on how you answered the question below (see screenshot):

If you entered the carryover loss in this field as a negative number, that could account for why the amount was added rather than subtracted.
