Happy to help, @jntcasey.
Allow me to share some information about tracking mileage in QuickBooks. This way, I can guide you accordingly.
Are you using QuickBooks Self-Employed (QBSE) app and QuickBooks Desktop (QBDT) for Mac? If so, these two platforms have different functions as far as tracking mileage is concerned. With the QBSE mobile app, you can monitor your company's mileage manually and automatically. Then, in QBDT, you can enter your miles by hand.
If you want to use the two programs in tracking mileage, then you're right that it's redundant. On that note, I suggest choosing a program that meets your organization's needs.
Check out the following articles to find out how this functionality works in both programs:
However, if you're referring to something else, let me know in the comment section. This way, I can provide the most suitable explanation and solutions.

I'll be waiting for your response. I want to make sure this is taken care of. Keep safe, jntcasey.
