Start in Federal Taxes >> Wages & Income >> 1099-MISC and Other Common Income >> Income From Form 1099-MISC. Click "Start" work through the interview.
After entering the info from the 1099-MISC, continue until you see the question about this being connected to your main job, and say "no." Check only the box for 2017 income. Then answer that this was not an "intent to make a profit." Those three answers should classify this as "Other Income", which will appear on Line 21 on Form 1040.
