1099-B Unknown Term Gains or Losses on gross proceeds

[CD61]

My 1099-B has an Unknown Term Gains or Losses on Gross Proceeds with no clarification  of long term or short term .  Only box 1d has the amount reported, all other boxes are N/A with additional information of CASH IN LIEU.  How do I enter this information?

Cash-in lieu transactions usually occur as the result of a merger or acquisition whereby instead of receiving partial shares you receive cash instead. You can use "Various" as the acquisition date. The amounts are usually small; therefore, personally I just use short-term and a zero cost basis. However, go back to your holding that was acquired and determine what the holding period and cost of the shares for which you received cash. For example, if you owned 100 shares of XYZ company that you bought for $100 a share five years ago and had no dividend reinvestment, and you received 33 shares of acquiring company abc, along with cash in lieu, you would know that your cash in lieu transaction was long-term and you cost basis was $100.
