The credit for the electric car is a nonrefundable credit. That is, it can be used to reduce your tax to zero, but cannot be refunded.
If your tax was already zero before the information for the car was added, then it would not have changed your refund, because the credit could not be used in this case. This may be your situation.
As for your 1098-T and 1099-Q, if your daughter is listed as your dependent, then you need to report both forms on your return.
The good news is that the American Opportunity credit (if your daughter is eligible) is partially refundable, so this may increase your refund.
