Thanks for getting back to us for sharing additional details about your concern, Elaine.

I understand how important time is in running your business. Currently, the option to delete an entire line in a report by right-click then delete isn't possible. 

As a way around, you can look for a third-party app that has the option you need. Just hover to the App Center inside your QuickBooks Desktop (QBDT) and look for an app from there.

Furthermore, I've added this link that you can use for reference in case you'll need to access your report outside QBDT: Export reports as Excel workbooks in QuickBooks Desktop.

You'll have my attention whenever you need a hand running your reports and transactions. Just leave a reply in this thread and I'll get back to you as soon as possible. Have a good one!
