How do I add additional filters in a custom report?

I'll help you add multiple accounts, NameUser.

Let's personalize the Profit and Loss report to add the multiple accounts. I'll show you how:

1. Go to Business overview, then select Reports, or go to Reports.
2. Locate and open Profit and Loss.
3. Click Customize.
4. In the Filter section, click the drop-down arrow beside the Distribution Account.
5. Place a checkmark on the accounts you want to select.
6. Click on Run report.
7. Once done, click on Save customization.

For more details, please see this article: Customize Report in QuickBooks Online.

If the accounts are still missing, let's access your QuickBooks Online account via a private window. This is a great place to determine if this is a browser-related issue. Here are the keyboard shortcuts: 

• Safari: Command + Shift + N 
• Google Chrome: CTRL + Shift + N
• Mozilla Firefox or Microsoft Edge: CTRL + Shift + P 

Once signed in, save the report again. If it works, let's clear the browser's cache. Doing so helps us improve the program's performance. Otherwise, I'd recommend using other supported browsers.

Additionally, I've added articles that'll help you learn more about what you can do with your reports to get the details needed: 

• Common Custom Reports in QuickBooks Online
• Export your Reports to Excel from QuickBooks Online

Please keep us posted if you need assistance in running and customizing your reports in QuickBooks. We want to make sure you'll be able to filter the correct details.
