My 1099 includes all mileage and public transportation costs for the year. How to exclude that from my labor?

You have to file as self-employed.  It is very common that a contracting service will include all gross amounts they have paid you on the 1099-MISC, and then you must expense them out on the Schedule C.  You will be able to use "Transportation" or a similar category to list these expenses.  This is how the amounts are subtracted from your taxable income.
