I clicked on what I think might have been a scam email

Without being able to see the link we can't say for sure, but it's very possible that it was a scam and that you've given some crooks your Amazon login information. Immediately go into your Amazon account and change the password. If your normal password no longer works, then your Amazon account has almost certainly been hijacked. Contact Amazon Support for assistance.

If you use that same password on any other accounts - a very bad idea - immediately change those passwords.

Good luck.

If it's a phishing scam as it appears to be, they were trying to get your Amazon credentials. Since you changed the password, your account should now be safe, though you should monitor it carefully to make sure no orders that you didn't place come through. However, since if this was a scam the scammers now know they have a valid email address, you may now get plagued with spam and other attempts to scam you. You should never provide account credentials or any other personal information in response to any unsolicited or unexpected contact, whether via email, phone, or text. That's how scammers work; to try and fool you into giving them your information.
