You will not owe the IRS, as your refundable credits will more than offset your taxes. The IRS will, most likely, be sending you money.
You will receive a form 1099-Misc, from Postmates (the $600 rule). The
IRS considers anything in box
7 of 1099-MISC to be self employment income. Enter the 1099-Misc
income, at Other Common income / income from a 1099-MISC . TurboTax (TT) will
complete Schedule C or C-EZ for you and allow you to deduct any expenses
associated with this income. You'll also have to pay self employment tax
(social security & Medicare) on any profits greater than $400.
Your mileage is deductible at 53.5 cents per mile, as expenses to reduce the taxable income.
Your net income is earned income for the Earned Income Credit and Additional Child Tax Credit (the "refundable" tax credits)
