How to find the save files for GTAV - Rjaa

So I downloaded the game today and wanna use a save file I found online but can't seem to find it. No, it's not under Documents, Rockstar Games, GTA V and no, it's not under Appdata, Roaming, Social Club something, GTA V. Although both of those folders exist, they seem to have no effect on the game so I'm assuming that theyre old folders and not for this instance of GTA V.
