entering receipts

brsdb3381

I have a couple of Semi Trucks and every month get an envelope of random receipts. Most are cash spent at truck stops, toll roads etc... how do I manually enter them and how do I set up an account for this purpose.
Also my settlements show all the insurance and normal deductions but Chase only shows what made it to the bank. Do I add categories and plug them into the split categories or will it foul up everything?
