How can I find mileage out of country phone is lost

Hi there, @chelsea6. 

It's sad to know that you've lost your phone. You can Log in to https://selfemployed.intuit.com/login in a web browser on your computer and use your QuickBooks Self-Employed credentials. Then, go to the Miles tab to review your total miles driven and also your mileage rate. 

I'm adding these articles for your reference:

• About the Miles page and vehicle info settings
• Learn how QuickBooks Self-Employed calculates your mileage deduction

You're always welcome to post again if you have more questions. Have a wonderful day!
