Not sure if I paid a car registration fee. Where would I look to find out?

It would generally be shown on the document showing where you registered the vehicle to get the license plate for your state.  The fee you had to pay for the license plate that is based on the value of your car is the car registration fee.

Only the following states charge a fee based on the vehicle value:

Alabama
Arizona
Arkansas
California
Colorado
Iowa
Indiana
Kentucky
Louisiana
Massachusetts
Michigan
Minnesota
Mississippi
Missouri
Montana
Nebraska
Nevada
New Hampshire
South Carolina
Washington
Wyoming
