Deductions & credits

So this did give me an idea through. I played around with the question and entered different details into TurboTax until it finally gave me the credit and then looked at the generated Form 8911 to see what it did for a calculation.

 

Turns out I don't qualify for the Alternative Fuel Vehicle Refueling Property Credit due to my Tentative Minimum Tax (TMT) which is used on Line 15b of Form 8911 to calculate my Net Regular Tax. Since my TMT was too high, it causes my Net Regular Tax to go negative so I therefore do not qualify for the credit.
