ATT login redirects to Directv account

I only have fiber internet form att. I downloaded my Directv streaming app months before I signed up with att fiber. Previous internet provider was different when I did join Direct. So, I do not believe the att and Direct accounts merged, since, in my thinking, neither knows of the other. Yet, both on my apple phone and laptop, when I login to att to look at my internet account, I am auto sent to my Directv account. Strange, both have att logo.

HELP!
