We have an open investigation for tracking mileage when exporting the data. You can reach out our QuickBooks Self-Employed (QBSE) customer support to add your account to the list of affected users so that you'll be notified once resolved.

- Press Ctrl + Shift + N for Chrome.
- Hold down Command + Shift + N for Safari.

Please let me know if you have any other questions. We're always here to help.
