Glad to have you here in the Community, @AdminAF.
We have a designated support team that can help delete or edit your filed GST return. And I'd be glad to redirect you to them to get this resolved right away.
Since the QuickBooks software doesn't have an option to delete or edit a filed GST return, I suggest contacting our Customer Support Team. They have the tools that can check your filed GST return and help you delete or edit it. They can also provide some guidance on correcting your GST return. To reach out to our support team, please follow the steps below:
- Sign in to your QuickBooks Online account.
- Click the Help button.
- In the QuickBooks Assistance chatbox, select Talk to a human and choose I still need a human.
- Hit Contact Us.
You can also check out this article for another way of reaching out to our support team and its support hours: QuickBooks Online Support.
Once you successfully filed your correct GST return, you can read this article to learn how to record your GST payments: Manage GST payments in QuickBooks Online.
Please know that I'm just a reply away if you need any further assistance managing your GST return. Thanks for coming to the Community, wishing you continued success.
