I got here steps that can help you view further mileage entries.
When managing your trips, you'll have to set the correct date range. I'd recommend selecting Custom Date and setting the date range. Then, you can click Yes to confirm the period. This will now show the trips that you want to change.
Here's how:
Go to Mileage tab,
On the tax year drop down select the custom date option.
Select a start and end date to view a list of trips taken during that time.
