Welcome to the Community. I'm here to help you renew your QuickBooks subscription.
If you're referring to the activation code sent to a different email address or if you encounter issues with it, I recommend contacting our support team. You'll need to send an email regarding the concern from this page: https://contactus.intuit.com/en_IN/contact.
The system sends the renewal link to the email address attached to the account. I suggest keeping the information up-to-date by changing the information to the recent one you have.
Here's how:
Sign in to QuickBooks Online.
Click your account profile next to the Gear icon in the upper-right corner.
Select Manage your Intuit Account.
Go to Sign in & security.
Update the email address.
If you're referring to something else, please let me know. You can add more details by leaving a comment down below.
