I had the same is where on CA540 Line 74 Excess SDI was always red. The number did agree with my W-2. We deleted the W-2 Line 14. We entered $0. We renamed the entry from CASDI-E to SDI. In the end. We deleted the California return. Saved with no California return. Reset the W-2 Line 14 entry to its original entry. Then reinstalled the California State return and the original Line 14 entry was accepted.
Delete California return, reinstall California return. That is the fix. For me. Good Luck
