Thanks for taking the time to add a screenshot to this thread, @userleanadeklerk1412.

Let me join in this conversation and help you accomplish your task in QuickBooks. 

Sometimes too much cache stored in a browser can cause the authentication error message. This might also be the reason why the VAT detail report isn't showing the supplier's VAT amounts. 

To verify, let's run some basic troubleshooting steps. Let's start by accessing your account using a private window. This doesn't save your browser's history and will help us isolate the issue. Simply press the following shortcut keys to access this mode: 

• Ctrl + Shift + N (Google Chrome).
• Ctrl + Shift + P (Firefox).
• Control + Option + P (Safari).

If you're able to add the screenshot or see the VAT amounts, go back to your regular browser and clear its cache. Alternatively, you can use other supported browsers if the issue persists. 

Additionally, you can customise reports in QuickBooks. This way, it would be easy for you to review the details that matter the most to your business. 

Let me know if there's anything else that you need about this or with QuickBooks. I'll be around to lend a helping hand. Have a good one!
