The Trial Balance report is designed to show all running balances of the accounts. This report summarizes the debit and credit balances of each account on your chart of accounts during a period of time.
To get this sorted out, you might want to pull up and customise the Profit and Loss and Balance Sheet report. This way, you'll be able to see the revenue or expense of each account within a specific period.
From the left menu, click Reports.
Search for Profit and Loss or Balance Sheet.
In the Report period section, select the specific month you want to show.
Click Run report.
I recommend customising the report to get the specific details you need. You can also memorise it to save its current customization settings. It serves as your record and helps you quickly access it for future use.
