Question about how to renew license plate with no personal property tax receipt (first year after moving from another state and was not billed for property tax)

I am trying to renew my license plates online, but it says it cannot verify receipt of my 2020 personal property tax. The problem is, I was never billed for any 2020 personal property tax and so have no receipt. I looked it up in the online system and just says no information available.

I just got a PPT *declaration* form a couple weeks ago, which I also submitted online, the purpose of which was to inform the city that I own a vehicle (they had no record of it). That form said 2021 though, so I don't know if that's for last year or this coming year. I registered the car after moving from out of state one year ago in January 2020, and of course I didn't have to pay taxes at that time.

So the question is, was I supposed to get a property tax bill for 2020, and did they make some mistake in not putting my vehicle into the system when I registered it a year ago? Do I have to go to City Hall again and try to get them to bill me for 2020 taxes just so I can renew my plates, or get another waiver because maybe I wasn't required to pay?

**SOLVED:** Per someone's advice below, I was able to renew in person at the DMV (did not have to go to City Hall) using the same waiver I had gotten when I first registered the car. The waiver stated that property tax was to begin in 2021 which means I wasn't expected to pay 2020 taxes.

I had never seen this explained before so don't know if this is everyone's experience. If you registered initially for two years, assuming that was an option, then I guess this wouldn't be an issue because you would have paid the taxes by the time you were up for renewal.
