When filing my state return do I need to re-enter all of box 14? how do i know if it came over from the federal return?

Assuming you are referring to Box 14 of Form W-2, it is used to report amounts that don't belong in other boxes on Form W-2. Employers can use it to report additional tax or income information for filing or informational purposes. Some employers use box 14 to report amounts deducted for State Disability Insurance taxes or union dues that may be tax deductible. See this TurboTax help article for more information.

Enter all of the information on your Form W-2 in the Federal section of TurboTax. After you have completed the Federal return, when you start a state return, all of the information will transfer to the state return. Each state return in TurboTax has an interview section where any information is requested that would be needed to make state-specific adjustments to the information entered in the Federal section.

You can preview your return before filing to review the forms that TurboTax has prepared from your entries and to find out how your taxes were calculated. See here for details.
