Thank you for visiting the QuickBooks Community. I can share steps to ensure you'll be able to print your mileage data for 2021.
For now, printing directly your mileage record for 2021 in QuickBooks Online is currently unavailable. However, you can download trips from QBO to your computer as a CSV file by going to the Mileage menu. This will open a report in an Excel file that shows all the trips in 2021.
Lastly, you may refer to this article to see different details on how to set up the QuickBooks mobile app and your device to track trips accurately to resolve missing or inaccurate trips: Fix mileage tracking issues in the QuickBooks Online mobile app.
