If your California return was rejected with Rule Number F540/NR/NRS/2EZ-170 (or 180), the California Franchise Tax Board (FTB) is saying the amount entered as the Prior Year Adjusted Gross Income (AGI) is not matching their records. It is possible California's records are incorrect, but you can still e-file the state return.
