Changing the thank you link will not send the email notifications to a different email address, what you need to do is change the email recipient address.
Here is a guide that will help you with that: How-to-Find-and-Change-the-Email-Address-Used-for-Notification-Email
However, if you want to also change the thank you page and set up your custom link, this guide will help you: Setting-Up-the-Thank-You-Page
