Thanks for joining this thread, @ecovert_789.
I appreciate you following the steps provided by @IntuitHeidi. Allow me to chime in for a moment and share some information about the issue you're getting when removing unbilled expenses in QuickBooks Online (QBO).
This has been reported as an ongoing issue with an investigation number INV-16307, and our Product Engineers are now working to fix this as soon as possible. While we don't have a firm timeline for when this investigation will be resolved, I highly suggest you contact out Phone Support team. They have tools that can add your company details to the list of affected users.
Once added, we can immediately notify you once the issue has been fixed and provide you the resolution. I'll also update this post as soon as I get a message from them.
Here's how to reach them:
1. On your QBO account, click the Help icon at the upper right.
2. Select Contact us at the bottom to connect with a live support agent.
That should point you in the right direction. Thanks for your understanding and patience while we look into this. Please post again or leave a comment if you have any follow-up questions. I'm always here to help. Take care!
