We haven't received any reported case about scrolling problem with the QuickBooks Self-Employed (QBSE) transaction register through Safari. You can perform some troubleshooting steps to isolate the issue. I'm here to guide you with the details.
First, open your QBSE account using a private window. In most cases, unusual behavior like this happens due to the stored cache on the regular browser you're using. For Safari, use this keyboard shortcut: ⌘ + Shift + N. For other browsers:
Google Chrome: Ctrl + Shift + N
Mozilla Firefox: Ctrl + Shift + P
Microsoft Edge: Ctrl + Shift + P
If it works fine, go back to your original browser and clear its cache to start fresh.
For additional resources, while working with QuickBooks in the future, you can open the topics from our help articles.
