My state tax filing is accepted with refund, but from the state web site is showing I owe. Maybe turbo tax made mistake on tax withheld. How come this can happen?

My W2 shows less than what is typed in CA tax return form. Not sure how this happened in Turbo tax.

All entries within TurboTax come directly from manual entries or imports. Therefore, TurboTax would only include items on the tax returns as entered.  

If the state taxing agency makes any changes to your return, they will mail you a letter letting you know of any adjustments and will give you an option to reply and provide proof of your entries on your tax return.  Please see this link from the FTB for more information on what to expect.

If you feel the error was due to a calculation error, please see this link for guidance on submitting a claim.
