Unfortunately, we do not have the functionality to check to which email you have linked your account.
If the account was accidentally linked to the wrong email, you may check which one is using the email in the Google Accounts Settings and for which apps.
To find accounts linked to Gmail you can do the following:
1. Go to your Google Account Settings.
2. Click on Security in the menu on the left.
3. Scroll to Connected Third-Party Applications and Services.
4. Click See All Connections.
