I'm cleaning up the COA due to too many redundant accounts - when I try to make an account inactive (after running the report and finding no data) I get a message stating that at least 1 product or service is using the account; which is making it so I can't inactivate that account.  Then when I go to the product and services list and check all of the income accounts and expense accounts each product is attached to, I cannot find the account in question. Yes, I've used the filter to list ALL accounts.  Anyone have a clue how to resolve this?  Thanks in advance.  

PS - I chatted with a QB expert and they couldn't figure it out either.
