Get your taxes done using TurboTax

I am a season ticket holder who cannot attend all the games so I post them via SeatGeek to sell.  I was using Personal items sale.  I lost more than I made (overall), but 2 of the 4 sales ended up making me a whopping $20 total (one sale alone lost over $100, but that just zeroes out for tax purposes).  Should I click the button about some of the sales were done at a loss?  And once the info is entered, I then go into the section and post all the transactions for the sales.  When I Smart Check, I get:  Form 1099-K Wks (SeatGeek, Inc.): A link to Schedule C or another source for the amount reported in box 1 must be selected.  To associate this amount with an activity on Schedule C, D, E, F, or Form 4838, double-click on the field provided.  Otherwise, check the box that applies to this income. If the amount was reported in error, there is a box in the reconciliation section below for that purpose.
