First, are you putting your business revenue and expenses into Schedule C as you should? You can definitely use Schedule C and still claim the Standard Tax Deduction which is $12,950 for single filers, $25,900 for joint filers, or $19,400 for heads of household.
I am concerned that you may be confusing the standard mileage rate deduction (which is used on Schedule C) with the Standard Deduction which is used on Form 1040.
