Quickbooks says it's fetching my data but just keeps spinning.

You've posted in the right forum, Icdopke. I'll help you fix the "QuickBooks is fetching my data" error so you can continue with your business tasks.

Before anything else, I'd like to know the specific area in QuickBooks Self-Employed (QBSE) you encountered this kind of error.

In the meantime, we can execute some basic troubleshooting steps to fix this. Let's begin by accessing your account via incognito or private mode. In this way, the browser won't store cache data files that cause unexpected errors in the system.

Feel free to utilize the shortcut keys below: 

• Google Chrome: press Ctrl + Shift + N
• Microsoft Edge: press Ctrl + Shift + N
• Safari: press Command + Shift +N

Then, access your (QBSE) account there. If this works, clear the cache of your default browser to remove accumulated data files. 

If the issue persists, you can use another supported browser or device to see if your operating system fits with the QuickBooks requirements.

I've also included this article to see how the program tracks everything throughout the year.  QuickBooks Self-Employed Overview
