I used Quickbooks 2016 Desktop until recently. When I would run a financial report, I could click on one of the line items, and QB would present the detail behind it. For example, in a P&L report, if I clicked on Sales, I could see a list of the customer deposits that made up the Sales. 

I finally purchased QB 2021 Desktop this year. However, the new version doesn't seem to have this very convenient feature, or I can't figure how to use it if is still available. Thank you for your help.
