When you register with the SB100 process in California, the vehicle owner has 2 options for registration: 1) register the car with manufacturer's date of the vehicle it represents (1957 Porsche for example) OR 2) the year the car was made by the manufacturer, in your case JPS 2020.
Naturally, almost all owners choose option 1, since no smog test is required for the life of the vehicle. I suggest you check your documents to make sure you haven't chosen option 2 by mistake.
As you progress with registration, please keep the group informed. That's how we all learn.
