How to add Journal Details to Profit and Loss Report?

I can help add some details to your Profit and Loss report, @blaine5.

You can select the Add notes to enter journal details on the Profit and Loss report. By clicking the Edit titles, you can also insert other parts on the default accounts like Income, Expenses, Gross profit, Other income, etc.

When you want to select and check the details on the profit and loss, you can click the amounts under the Total column.

When you want to run and manage your reports to show specific accounts or customers, you can reference this article on how to format and show its data: Customize reports in QuickBooks Online. It includes how to share custom reports.
