Hi there, @wh6372. We'll share data about integrating third-party apps into QuickBooks Self-Employed (QBSE) or any QuickBooks product.
Before anything else, we'd like to ask what app you used to track your mileage. Also, if you're using QBSE, please be aware that the option to integrate any third-party application is unavailable. On the other hand, if you're using QuickBooks Online (QBO), you'll want to contact your Mileage app support team so they can help you integrate the app into the program.
Furthermore, we got these articles to help you fix mileage-related issues when using the mobile version of QBSE and learn more about the automatic mileage tracking feature:
The Community space is open 24/7 if you need further assistance managing mileage, @wh6372. Feel free to visit us anytime so we can help you out. Stay safe, and have a good one.
