You should say you use the Cash Accounting Method and all income is At Risk. Just enter the total as Other self employment income or as Cash or General income. You will need to pay Self Employment tax on it in addition to any regular income tax.
You can enter Self Employment Income into Online Deluxe but if you have any expenses you will have to upgrade to Premium version. Or use any of the Desktop CD/Download programs.
