Hello, jenniferwiech74.

I appreciate you for sharing the troubleshooting you've performed on your end.

I'd recommend reaching out to our Customer Care Team via chat or call. They can do further investigate the root cause of the error.

You can report this issue through it, too.

1. Sign in to your QuickBooks Online company.
2. Select Help (?) at the top right.
3. Select or type Contact Us.
4. Enter your concern, then select Let's talk.
5. Choose a way to connect with us.  

Once our Customer Care Team added you to the list of affected users, you'll receive email updates directly from our engineers.

For future reference, you can check this out if you want to run and save a monthly expense report by the vendor.

Loop me in if you need anything else. I'll be here to help. Take care.
