Write of mileage deductions

Yes, however you should combine the income for one business and enter it there. You should not have two Schedule Cs for the same type of activity.  If necessary you can delete the 1099-NECs and enter the income directly in your business activity as 'Other, Cash, Check, etc'. 

First delete your 1099-NECs and next enter your self employment income and expenses in one business activity.
