The zeros you see on the California adjustments screen appear to indicate that you didn't make any California adjustments, which would be correct if your income and expenses are going to be treated the same on your California return as they are on your Federal return (Schedule C business, not employee).
You appear to be using a Desktop / Download version of TurboTax, so you can go to Forms Mode by selecting Forms at the top blue bar, and looking at the list of forms on the left side, choose those you would like to check over to make sure your income and expenses are picked up on both returns. A good form to look at for California returns, in addition to your Form 540, is Schedule CA, which summarizes the differences between your Federal and State returns.
