You are not required to pay any federal income tax since your total income was less than the standard deduction. However you must pay self employment tax on all self employment income above $400. It is double because a self employed person must pay both what the employee pays and what the employer pays which totals 15.3% of net income. When you get a W-2, you only pay what the employee pays and you never see the amount the employer pays.
You had to pay to upgrade to Deluxe because you had to enter the 1099-MISC which can't be entered using the Free Edition.
