Hello, @jgatlin77. Let me share some details about expense and mileage reports in QuickBooks Online (QBO).
In QuickBooks Online, the mileage report can be pulled up by clicking on the Download Trip button from the Trips page. This will open a report in an Excel file that shows all the trips that you've entered.
To do that, you can open the trips page and press Download Trips.
See the screenshot attached for your reference:
If you want to run the expense report, you can follow these steps:
Navigate to the Reports tab.
Search for the Expenses by Vendor Summary Report.
After opening the report, you can filter the Report period for your desired dates.
Click Run report.
You'll also want to share more information about your post if you have further concerns. We'll make sure to sort it out for you.
