Hm, nobody seems to answer the obvious question of the OP. I know that the folder location can differ based on the OS.
This is where downloaded add-ons and your own add-ons should be (WINDOWS): C:\Users\YOUR USERNAME\Documents\my games\Wesnoth1.18\data\add-ons
In older versions there was an option to directly save the files inside the game folder.
Can't say how this is handled on Linux or Mac. Another trick in case you use older versions is to go into the map editor and there you can browse to the add-on folder as well.
