As a stockholder of a company, I got rights to purchase additional stock, which expired as I did not opt for it. TT imported these transactions from 1099-B. On 1099-B these transactions are reported as 'Expire' with zero cost basis, zero proceeds and zero gain/loss. TT imported these as 'Sell' transactions and prompting to select investment type. There's no implication on tax but how do I accurately report these as 'Expire' transactions in TT? What should be the investment type?
