i've bought minecraft both on console and ios and i cant log into my minecraft account

i've bought multiple versions of Minecraft yet its frustrating that Minecraft.net will not let me log into my Microsoft live account to access my Minecraft account. i would not like to purchase the java edition figuring i do not have a computer of any sort. but i would like to have access to my Minecraft account. i believe i've previously had a Mojang account yet i have no sort of access to it as well. Please help !!
