Somehow I signed up for an account using onedrive and I don’t see a onedrive login option. When I login with my attached office 365 it goes to a completely different account. How the heck can I log back in using my onedrive login?

If you find that Office is bypassing that step, then it may be because your are signed into Office365 with your corporate account. So first sign out from Office365 and try it
