Let me ease your confusion, 2c458c18c020.
Once an account is canceled, we keep your data for a year after the cancelation, before it'll be deleted permanently. Even if it's canceled already, your Intuit account is still associated with the email address. It is the reason why we have your email address or number on our records.
You can log in to your Intuit account and make some changes there. If you're unable to do so, you can reach out to our customer care support so you can unlink the email address. You can open the link I've provided and select the QuickBooks product (Online or Desktop).
Feel free to visit us if you have other concerns. We're just one post away. Take care!
