The first step is to click on Achievement on the menu on the left hand side of your screen.
Once on the Achievement page, you will see a History tab at the top. Click on this tab.
Once on the History page, you can filter by time period, achievement name, user or team to find the achievement that needs to be removed.
Once the correct achievement is located, you will click on the ellipsis on the far right of the achievement and select Delete. This will delete the achievement from the user's profile and remove any coins associated with it, if any.
