If you "worked" (provided a service) to get this money, then you need to report it on a schedule C and pay income and and self employment tax.  If you don't, the IRS will send a letter demanding payment of tax with interest and late fees.

To prepare a schedule C you must upgrade at a minimum to the Deluxe version.  If you have expenses, you need to upgrade to the self-employment version to deduct your job expenses.  Since you owe income tax and self-employment tax on the net profit (income minus expenses) you may want to consider whether the upgrade will pay off.
