Hi there,LCP Builds. 

Allow me to share additional information about expense transactions not showing in the project overview in QuickBooks Online. 

Have you tried performing the suggested steps on this thread? If so, I recommend reaching out to our Customer Care team. They have the tools that can help investigate and identify the root cause of this matter and apply a resolution.

Here's how to do that:

2. Type in "Talk to a human", then press Enter.
3. Look for I still need a human and click on it.
4. Click Get help from a human or Contact Support Team.
5. Select between Send a message, Schedule an appointment, or Get a callback.

Please be reminded that our Support Team is available from 6:00 AM until 6:00 PM on weekdays, and from 6:00 AM till 3:00 PM on Saturdays.
