How can I get P&L report from One line quick book

I'd be glad to help you access your P&L report in QuickBooks Online (QBO), @parvizd1333.

The P&L reports summarize your income and expenses for the year. You can run the report in any version of QuickBooks Online.

Here's how: 

1. In your QBO account, go to the Reports menu.
2. In the Find report by name field, search for Profit and Loss. 
3. Select the Report period. 
4. Click Customize to configure the rows, columns, and filters if needed.
5. Once done, click Run report. 

If you want to use the reports outside of QuickBooks, you can export them to Microsoft Excel.

Don't hesitate to comment down below if you need further assistance in generating reports in QBO. I'm always here to help you. Have a nice day.
