Hello there, @janice3.
Thanks for taking the time to reach out to the QuickBooks Community. I'm here to help provide some insights about the QuickBooks Advanced.
If you're referring to the pop-up product offers to upgrade your service to QuickBooks Advanced, you can manually close it since there isn't an option to permanently remove it as of the moment.
However, if you'd like to downgrade your service from QuickBooks Advanced, to do this, you can follow the detailed steps in this article: Downgrade your QuickBooks Online subscription.
If you're referring to something else, please let me know and I’ll be sure to get back to you. Have a good one.
