A long time club (with bar) had to close permanently during covid epidemic. They sold the club building in 2023. A client, who was regular voting member/owner, received 2023 1099-B marked as following: Box 1D, Gross proceeds: (approximately) $10,000.00 Box 2: SHORT TERM GAIN BOX CHECKED. and that is it on form. no dates, no cost basis, no description of property. All client paid was annual dues over the many years. It looks like no cost basis? Also, I am not sure why it was not marked as a LONG TERM GAIN, INSTEAD OF SHORT TERM GAIN?. (I think payout to each member was based on how many years each was a member, but not 100% sure). Thanks.
