I have done all the steps above, and when I get to review my entire filing, I get a "needs review" screen that I cannot get past. It says, "Loss from sale of personal property is not yet supported in this release of Turbo Tax. Support for this situation will be provided in a future release." So, it won't let me file because it doesn't seem to like the total amount of payments and payments for personal property sold at a loss to be the same (I guess).
I have the same situation as the original poster - I sold tickets at a loss on Ticketmaster and received a 1099-K. So I don't know where to go from here.
