Am I missing something about how CA State AMT is calculated, I am getting none due no matter how many I test- is there no AMT due on options exercised, held and NOT sold?

IN TT Federal behaves as expected - increasing after a threshold is passed. However for California state tax calculation it does not matter how many options I exercise that cause the beneficial value to increase significantly (from $0 to $40,000) it never increases the CA state tax. This does not seem right? Am I missing something about how CA AMT is calculated - eg is there no AMT due on options exercised, held and NOT sold in a given year? Or has Turbotax not yet got the CA part of the return  working fully for the 2024 tax year - thanks
