With TCM Logos, no need to create a "graphics" or "logos" folder. They are already present in the downloaded folder.
There are 3 folders (from the extraction) to copy / paste into the Football Manager 2020 folder: "ads", "graphics" and "TCM20 Instructions".
There are also check / uncheck boxes in the interface options (everything is explained on the instruction image present here, on the official website or in the "TCM20 Instructions" folder).
Also pay attention to the installation path if you are on MAC, it is different than on PC.
