I got an assessment for 2016 taxes from California showing a different taxable income than my return. They want to assess $2,500. What now?

State that you disagree and send them COPIES of your paperwork along with a letter stating your position.

TurboTax does not receive any information from the IRS or your state after your return was filed, so no one at TurboTax knows about a letter you received from the IRS or the state.

AUDIT SUPPORT

TurboTax has a special phone number for help with IRS/state tax letters, which will be easier than going through regular Customer Support.   At the page below, click on the blue button that says "Get Help from TurboTax Support".  Then it will ask you what tax year is your letter.  Then it will ask you what the letter concerns. Then it will show you the phone number during posted business hours.

and Amy is jumping the gun by assuming the state is wrong.  maybe they are maybe they aren't.  there's no way for her to know because she can't see your return or documents.
