Instagram Connects to the Wrong Account, Unable to Access My Old Profile

I can access my Facebook account, which is linked to my Instagram account, but Instagram keeps redirecting me to another account instead of the one I’m trying to access. I created the old account as a child and no longer remember the password. When I use the “Log in with Facebook” option, it connects to my current Instagram account, but I need access to my old account.

I know the name of the old account and can provide as many details as needed to prove ownership. I want to retrieve that account to access childhood photos and manage its visibility, as people searching my name find it and see outdated posts.

I request Instagram’s support team to help me recover my old account and allow me to manage its settings.
