If your work place has the mileage you can enter that, but to claim the other items you will need the costs. If you paid with a debit or credit card, you can check your statement online to see those transaction costs, or you could possibly contact the stores to see if they have that information. Either way you will want to be able to have some way to reference the costs in case of an audit.
