Hello there, @mariel121.

You may be experiencing some browser hiccups. We'll perform some basic troubleshooting to fix it. Let's start with logging into your account through a private browser. This will help us determine if the problem is related to the browser's settings.

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

• For Firefox, press Ctrl + Shift + P.

• For Chrome, press Ctrl + Shift + N.

• For Safari, hold down Command + Shift + N.

Once logged in, try to import again. If it's work go back to your regular browser and clear its cache to refresh the program. 

Moreover, you can use a different browser to narrow down the issue: System requirements for QuickBooks Online.

Please know that you can always get back to us if you have other questions. I'm always here to help.
