If you do see that you're getting charged for something that you didn't subscribed contact Adobe Customer Care directly. It will bring you to another landing page, check if there are any billing discrepancies. If you're able to login online, click on 'View Plan Details'. If you created an AdobeID your login is the primary email address that you used to associate it wit the AdobeID. I can find no such file/folder anywhere on my Mac.)

(Some other 'solved' post on another site suggested navigating to Library > Adobe > SLStore and turning something off. I am trying not to rant about how BigBrother intrusive this is. How do I possibly turn off this incredibly annoying 'feature'? Thank you to anyone that can help. There IS NO 'red cross button' on the top left. The sign in pop-up still persists and there is no way out of it. NOW, every damn time I want to open one of the hundreds of simple PDFs I've created over the years I can't just double click on them (NOR does going to File > Open and selecting the file). I signed in/created the account via Apple as that was an option and I didn't want to use FB or Google. Turned out whatever the feature I had searched for *could* be turned out BUT only for a monthly fee. I recently created an Adobe account to use some feature Acrobat Reader said would be enabled if I signed in.
