What is the fine for submitting a 90-day report late in Thailand, and should I do it before or after my move?

Hi, I have been here since Covid started, always doing extensions. Once we started doing the 90 day reports I was doing them. My most recent 90 day report expired on December 20. How much will I be charged for doing that late? I am about to move and need to know if i do it before the move or after. My actual covid extension visa does not expire until Jan 24. They would not do my 90 day report when i extended the visa, they told me i had to wait.
