Hi, newbie here = I got a 1099-B from Ameritrade, my MEH stock went private and they bought my shares out at $17 a share - however doing my taxes, it is looking for purchase date/purchase price - I have owned them for a while and can't find the info in my Ameritrade acct, and this is not listed on the 1099-B - how do I know what to put on my tax return? Help! Thanks!
