The Idaho solar tax credit is available the first year of purchase. Thereafter, it is taken as a state income tax deduction on your Idaho tax return for the next three years. This could be the reason the credit did not appear.
Idaho's state income tax deductions are entered on line 15 of the Form 40. The amount is extracted from the Federal Form 1040 Schedule A, Itemized Deductions, line 5.
If this is your first year claiming the credit, you will enter the amount into TurboTax under the State taxes tab. You will navigate through the prompts until you reach the screen that contains Idaho's credit and taxes. Scroll down to the Personal, home ,and family credits section and select Start next the credit you wish to claim.
