How do I check if someone else is using my Apple Account?

The answer to that is simple and requires no AI response with multiple things to check:

• Go to Settings > [name on top], and scroll to the bottom. Any device signed into your account will be seen there. You can then remove the device and follow up by changing your password.
• Whenever in doubt, change your Apple Account password as seen in the link provided by KiltedTim.

Problem solved and no further action is needed to secure your Apple Account. To further investigate any other issues not related to someone using your Apple Account, you can use this Support Article:

While the above replies correctly answered the question asked, why do you think somebody else is using your Apple Account? Are you meeting any particular misbehaviors or issues with your Apple Account that concern you?
