I have this same problem. The different prompts are very confusing, even though I know how it is supposed to be reported. This is particularly a problem with TicketMaster as they charge fees to both sides of a transaction and only show the sellers fees to the sellers and the buyers fees to the buyers. I think the point is they don't want anyone to know how much they are making on the transaction. Seems clear they should be required to report on the 1099-K all the associated fees and cost basis if they have it (which in most cases they do). The information they are reporting is really insufficient--suggest writing your congressional representatives--that's about all they seem to respond to these days.
