I ended up doing some fun spreadsheet work to figure out all the numbers. Had my own records for costs I paid, payments I received and my fees I paid to Ticketmaster. Took the total monthly info provided on the 1099-K. Then deducted the amounts I received by month to come up with monthly buyer's fees. Then based on percentage breakdown for each month, came up with buyer's fees amounts per sale. Entering it all into TurboTax was a pain in butt but finally got it working correctly without errors. At least I know what to do going forward and will update my spreadsheet accordingly for this year's tickets. There really has to be a better way. If this is how they expect us to report on it, then Ticketmaster should be providing those breakdowns for us as opposed to only providing a monthly number.
