Welcome to the Community, @Matt115.
For the A/R Aging Summary Report, you won't be able to add columns to the report. You'll have to export the report to Excel so you can edit the information to how you see fit. Otherwise, you can run an A/R Aging Detail Report and add columns by pressing on the Customize Report button at the top-left of the window. Here's a Community Article that breaks down on reporting works in QuickBooks Desktop: Reports in QuickBooks Desktop.
