Can I find all the places where my Apple ID has been accessed?

If you visit appleid.apple.com, you can see where your Apple ID is currently logged in under the devices section. You should be getting an email every time your Apple ID is logged in to a new "place".

Had you searched through your historical emails looking for that?

The subject line will begin with... YourAppleID was used to sign

What website? That makes no sense. You cannot log in with your apple Id to any website except Apple's iCloud.com, appleid.apple.com, or the forums here.

How would you log in to a website unless it had access to Apple's own secure database of Apple ID login information?

The website may very well be a scam, and just setup to get Apple ID login information form you, but does not actually log you into anything, which would explain why there is no report of logging in.

If you visited such a website, the best course of action is to change your password at http://appleid.apple.com immediately.

I'll guess you are the teen and you're wondering if you're being monitored.

If you search here for teensafe, you will see discussions about it.

It works by allowing the "parent" to access your iCloud backups, not the phone directly. So, if you don't use iCloud for backups, you're invisible to the program.

But to answer your question, aside from being told you are, there is likely no way to know if you're being monitored.

The site claims that if you know the AppleID and password it can access messages (even iMessages), call logs, email, ect and remain invisive while doing so. It's called Teen Safe.

In which case, there would be no way to know if someone was accessing it through TeenSafe. There is no where to see Apple ID activity. Apple sends an email when the Apple ID is used to access one of its sites, or is used in an Apple Device. Teen Safe does neither.
