Once a tax return has been filed and accepted, TurboTax receives no further information from either the IRS or a State concerning the tax return.
The state notice you received should explain exactly why the state has determined that you owe taxes for tax year 2017. There should be procedures for you to follow if you agree or disagree with the assessment. There should also be a phone number for you to call if you have questions.
You can also use the TurboTax Audit Support Center and speak with a support agent who can assist you with understanding the notice you received.
Support is open from 5am to 5pm Pacific time, Monday thru Friday
