They said I put the wrong amount in 2021 ca tax line 17

You calculate the Ca tax , I just followed, how come it is wrong

These things happen when you are not familiar with your state tax rules.

On which CA form?   The 540 line 17 is  Calif Adjusted Gross Income.    If the state says it is wrong they must have changed something like the AGI from the federal return or some adjustment on California Schedule CA (540).  The state return flows from the federal return so it might be wrong too.
