Thank you for reaching out to the QuickBooks Community, Max. I'd be happy to share details on how inventory items work in QuickBooks and guide you through the steps to correct the asset value to $0.00.

An incorrect Starting value or an inventory quantity adjustment can cause a zero-quantity item to show a value on your inventory valuation reports. With this, I recommend reviewing and updating your Products & services to fix this issue. Let me show you how.

1. Navigate to the Sales menu on the left panel to choose Products & services.
2. Select the item and hit the Edit button under the Action column. 
3. Go to the Quantity on hand section and hit the Starting value link for more information.  
4. Choose Got it to confirm the action.
5. On the Inventory Starting Value no.START page, check the item details, and update the information if needed.  
6. Click Save and close.

Moreover, if you need to delete any adjustments, you can reference this article for the complete process: Adjust inventory quantity on hand in QBO.

Please note that editing inventory adjustment entries can impact your accounting records. We recommend working with your accountant to ensure everything is accurate. If you don’t already have an accountant, you can easily find one in your area through the QuickBooks ProAdvisor website.
