Why is my state income tax withheld not showing up, there is a value in box 17 on each W2?

Where is it not showing up?   Where are you looking for it?   Did you import your W-2, or did you key it in by hand?   Check your W-2 entries to make sure you entered boxes 15, 16 and 17 correctly.   

If your wages or withholding didn't transfer to your state return, go back to your W-2:

1. Select the Federal Taxes tab near the top of the screen.
2. Select the Wages & Income subtab.
3. Find the Income Summary screen.
4. Select Update to the right of Wages and Salaries.
5. Select Edit next to the W-2 that contains the state income and withholding in question.
6. Scroll down to Boxes 15-17 (state wages and taxes withheld) and check the following:
   • Box 15 State should contain the correct 2-digit state code. For example, if an Arizona resident wrongly chooses AR instead of AZ, TurboTax won't pull the info over. Check your US USPS state abbreviation here.
   • Box 16 Wages should contain the wages that were earned in the box 15 state. If this field is left blank, TurboTax sometimes transfers the box 1 (federal wages) amount, but not always.
   • Box 17 State Income Tax should contain the taxes withheld amount (the withholding) for the state in box 15.
7. Select Continue three times to save your changes. If necessary, repeat these steps for other W-2s.
