Hi there, KatyMike.

Thank you for visiting the QuickBooks Community. I'll be sharing troubleshooting steps to ensure you can open the link provided by my colleague and view the details of the articles.

I've tried to open the link you're referring to and I was able to route to the right page. With this, it could be the cache full of history and temp files caused unexpected behaviors like the link shared above takes you to the main help page. That said, I recommend logging in to your QuickBooks account using a private browser. This is to rule out the possibility of a webpage issue, and private browsing doesn't store local files or cache. 

Use these keyboard shortcuts based on the browser you're using:

• For Firefox or Microsoft Edge, press Ctrl + Shift + P.
• For Chrome, press Ctrl + Shift + N.
• For Safari, hold down Command + Shift + N.

If it works in incognito, you'll have to clear the cache of your regular browser. This removes the history or log of sites so you can start with a clean slate. If the steps above didn't work, use another supported browser as an alternative.

Lastly, you may refer to this article to see various details on how the Sales page shows you a great at-a-glance view of all the status of sales transactions like open and paid invoices: View sales transactions.
