Deductions & credits

I was in the positive for my federal. well over 1K. I was supposed to get 4609 for my electric car, but it only added 2665. I literally only have my W2, another form for work expenses, a non deductible for a savings account. None of those things should cost me almost 2k....**bleep** the IRS yo. Thats my money I am paying for the car, not someone else's.
