I appreciate you for sharing the details of your concern here in the Community space, @business30509. I understand how important it is to view the data of your profit and loss report by bank account. I'm here to share some information.
In QuickBooks Online (QBO), the Profit and Loss report is driven by income and expense accounts, so bank account data will be reflected on the Balance Sheet reports. That said, filtering your Profit and Loss report by bank account is currently unavailable.
However, you can use the Track locations feature to create a report that lists each account. This way, you'll be able to allocate each transaction you make to one of those locations/bank accounts.
Please know that this functionality is available in the QBO Plus and Advanced versions. To turn it on, go to your company's Accounts and Settings. Choose the Advanced tab, then click the Categories section to select the Track locations checkbox.![P&L1.PNG P&L1.PNG](https://quickbooks.intuit.com/learn-support/image/serverpage/image-id/81511i85009FB35D34717E/image-size/large?v=v2&px=999)
After that, set up a location for your bank account.
- Go to the Gear icon.
- Choose All Lists under the Lists column.
- On the Lists screen, select Locations.
- Select New.
- Enter the bank account name in the Name field.
- Select Save.

Once done, you'll have to manually update/edit your transactions and choose the location/bank account from the Location field's drop-down list. ![P&L3.PNG P&L3.PNG](https://quickbooks.intuit.com/learn-support/image/serverpage/image-id/81513i49075F4930B9C5B9/image-size/large?v=v2&px=999)
When completed, you can add a Location column to your Profit and Loss report to view the lists of transactions for your bank account.
- Go to the Reports menu.
- Search the Profit and Loss report in the search box.
- Select Customize.
- In the Customize report panel, select the Filter drop-down.
- Click the box before Location, then select the bank account in the drop-down arrow.
- Click Run report.

Please keep in mind that QBO is not designed for multiple books. That's why all of the income and expenses will be combined on the Profit and Loss report.
You can also track them by class, refer to this article to learn more about utilizing the class tracking feature: Turn on class tracking in QuickBooks Online.
