Admin Hub but can't login with G Suite

[Boyd Petrie]

I was trying to test out a Jira Service Desk application for my company. It logged me in and and I clicked on G Suite, thinking that would let me sign in with my G Suite credentials. But instead, it seems to have created an Atlassian org and made me the admin of it from my Trello credentials. However, my Trello email address is just an alias of my G Suite credentials. So I'm locked out of the admin hub because if I try to login, it's using my primary G Suite account email, not the alias that it initially created it with.

I'm sort of at a loss here on how to get access. I can no longer access Trello boards because it created a new account from my Atlassian/Bitbucket account, and this new account is not a member of those boards. 

Does anyone have any advice on how to fix this?
