Get your taxes done using TurboTax

TurboTax calculates the credit for use on your state return, but the credit is not entered on your federal or Idaho tax returns.    If you were to prepare a state return for California, the amount would be deductible on that return.     All of the state information is entered in the federal section, so the interview remains available in the federal return, but the credits that are generated are only deductible on state returns that allow the deduction.  

If you preview your Form 1040, you won't see that credit applied.   Preview Form 1040 in TurboTax Online.

Use Forms Mode if you are using the desktop software.   You will see Form 2106 in your return, but it will be marked as For State Only.  And no amounts from that form get transferred to your federal return.    @CamJon
