13.20A - should I fill it out myself?

I moved to Switzerland a couple of months ago, and I imported my car. i got the 13.20A form at the border, and today i went to the MFK to get everything tested. It failed since I didn't have original alloys on the car, and they noticed since my current wheels are ET 38 and not ET 40 - in my opinion an absolutely ridiculous thing to fail a car test on, but that is for another day.

On the letter I got explaining why I failed the test, they also wrote

"13.20A Speicherort 13.20A: N: Experten / Selbstimport / Tesla Model 3 (stammnummer) vervollständigen und ausdrucken ausführen".

Does this mean I have to fill out the 13.20A myself? I honestly didn't expect that

Somebody has to fill it out, it doesn't need be you.

But, anyway, wrong wheels will definitely get you a fail.
