I can't provide you any source on how the fine notices of this nature look like since I have never commited anything to amount a hefty fine like this, but every single official document, bill, notice or whatever you may call it in which requires someone to pay something to the government, you will find extensive details on the account numbers and where to pay. They are not forgetting or not including this information.

Like I have said before and will say it again, the Brazilian law firm Xitter has hired is either comprised of the freshest graduated lawyers that never worked with something like this, or they can't read, or they're intentionally playing malicious to avoid paying the fine and causing as much instability as they can on behalf of Musk.
