Greetings, @Hasan Tariq.
Thanks for posting your concern here in the Community. Let me walk you through creating a wastage report in QuickBooks Online (QBO).
Just to confirm, are you trying to create a report that contains deleted product items? If so, you can pull up the Product/Service List report and customize it to show the deleted items. Here's how:
1. Go to Reports menu at the left panel, then type Product/Service List on the search bar.
2. Select Customize on the upper right.
3. On the Filter drop-down, put a check mark on Deleted and choose Deleted on the drop-down.
4. Click Run report.
Once done, you should be able to see the deleted items on the report. For your reference, you may check out these articles for more information:
That's it! Please let me know how it goes or if you're referring to something else by leaving a comment. I'll be here if you need further assistance. Take care and have a good one.
