ok - as Pantszer says - there are two folders for addon aircraft.
OneStore folder is for all of the MSFS/ Asobo aircraft. Anything that either came with your purchase of MSFS (whatever the version) or that came free with any SU or WU (update that included a free aircraft)
Community folder is for everything else - scenery, aircraft, utilities, that you either buy or download free - aside from the Asobo stuff above.
OneStore content goes to that folder by itself - there is literally nothing that you will ever have to put into that folder. This is why the Community folder was created by MSFS - to keep the two kinds of content separate.
Most folks probably have the ‘Community’ folder (shortcut) on their desktop for easy access
