Hello there, @Kfagan41. Let's do some troubleshooting steps for you to access the invoice and receive the payment report. 

First, let's ensure you're connected to a strong connection. If the issue continues, let's open your QuickBooks account in a private window to rule out browser-related issues. Here are the keyboard shortcuts:

• Google Chrome and Microsoft Edge: Ctrl+ Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Safari: Command + Option + P

If you can successfully access the report, return to your regular browser and clear your cache. Occasionally, the accumulated cache and cookies in the system can become outdated or corrupted, leading to unexpected behaviors. You can also switch to other installed supported browsers, which is a good alternative.

After generating the Invoices and Received Payments report, you can customize and save the customization process by memorizing it.

I'm here available to help you, @Kfagan41. Please do not hesitate to return here if you require further assistance generating reports in QuickBooks Online.
