Mistake for creating account email

Try this:

Go to https://account.adobe.com/, login using your "fake" email.

Click "Change e-mail":

Depending on how you secured your account, you will need to do some security stuff, either approve the action on the Adobe Account Access app or enter the texted code or get the code from your secondary e-mail.

Change the mail to the correct one. If the e-mail has been verified, you got a mail to that address, and you approved that address. Which is quite difficult, when the address does not exist.

If this does not work, contact Adobe customer care: Adobe customer care can be contacted by beginning a secure chat session at https://helpx.adobe.com/contact.html?rghtup=autoOpen. Pop-up blockers need to be disabled! If the chat window fails to open, or is non-responsive, use a different device to start the interaction.
