To add expenses from trips you can expand the Trip Expenses button, and fill in the details.

Note: from trips you have mainly transportation expenses, if you want to access all categories add expenses from Numbers > Add Expense > Check the box for ''Show all categories'' - How To Add Expenses

Bonus: You can attach a picture of the receipt together with an expense record to get rid of your expenses paperwork.
