The default is found in the State column for estimates as 1 = 100% of 2025 tax (2024 rates) for the current year of Lacerte. You should be changing that for each of clients affected with a code of 6. IF you had selected 6 for the Federal then the program would have done the calculation you are now requesting. 

You can also go to Settings > Options > California Options > adjust to what you feel the program should use for your client base.
