Hi there, @AHSLV.

You may need to perform some browser troubleshooting steps. This is done to check if this is a browser-related issue.

You can begin with using an incognito browser. This can help us determine if this is a data issue. Below are the shortcut keys you can use to access one:

• Ctrl+ Shift + N for Google Chrome 
• Ctrl + Shift + P for Mozilla Firefox and Microsoft Edge.
• Command + Shift + N for Safari.

Once done, check if you're now able to e-file. If it works fine, clear your browser's cache to delete the cache files that cause unusual QuickBooks Online responses. If the issue persists, you can use another supported browser instead.

However, if the troubleshooting method still doesn't work, I'd recommend contacting one of our Customer Care Team. They have the tools to verify your account and help you get to the bottom of this. The support hours is Monday to Friday 6:00 A.M. to 6:00 P.M. PT, and Saturday 6:00 A.M. to 3:00 P.M. PT.

I've added this article in case you want to check your e-filling status in the future: Check e-filing or e-payment status.

I'm just a comment away if you other questions. I'll be here around to help you always.
