Thank you for getting back to the thread, @KimL23. Let me guide you how you can keep it from showing up as income.

You'll need to update the affected account of the item. You can follow the steps below:

2. From there click on the item and edit.
3. After that, open the invoice and remove the affected item
4. Re-enter the item.
