How do I input mileage from a past event?

Hello EmEssMarie2U. I appreciate you letting us know about the date situation on your mileage tracking.

You can enter mileage from a past event by signing in to QuickBooks Online using a web browser or your phone's browser.

Here's how: 
 

1. Log in to QuickBooks Online.
2. Go to All apps, then Expenses & Bills, then Mileage (Take me there).
3. Select Add trip.
4. Add the Trip date, Starting and ending locations, distance, and the purpose.
5. Select the vehicle you used.
6. Select Save.

If you’re unable to select a date using the Trip date picker, try manually entering the date in the MM/DD/YY format. Alternatively, you can save the Trip using the system-assigned date first, then update the date afterward.
 

Here's how to edit the Trip:

1. Locate the newly saved Trip, then click the Pencil icon or click it to edit.
2. Change it to correct Trip date.
3. Click Save.

If that still won't work, I recommend uninstalling and reinstalling the app, or switching to incognito mode or another supported browser to eliminate any stored data or cookies that may interfere with the normal process of the Trip Date field.

Please let us know if you need further assistance.
