In my two different versions (on two machines) if you click help, there's a "Registration" button. This will show what versions your machine shows as being installed. If there's a version installed that isn't registered, it should say so. You should be able to click on the unregistered one, and the "Register" button should turn on, to let you click straight to the Symantec Registration website.

There may be some variation with different versions, and of course this is what you get when all the basics are okay.

If you didn't uninstall an old version before installing a new one, your computer may not know what version(s) you have. This will definitely confuse the issue. If that's a possibility, uninstalling all Norton versions, and reinstalling the one you want to use should clear things up.

Registrations and Subscriptions are handled by "nontechnical customer support" which is a bit tricky to locate on the Symantec websites. They seem to rely on the link that should pop up when you install, or the link that pops up when your subscription is about to expire, and assume that otherwise you only need tech help.

At Norton Customer Service there's a button for "trouble with subscriptions" that should include help with resolving registration problems, although I can't offer any guarantees.
