Unknown Term Gains or Losses on Gross Proceeds" on 1099-B: Proceeds from Broker and Barter Exhange Transactions.

I have a transaction under "Unknown Term Gains or Losses on Gross Proceeds" on 1099-B: Proceeds from Broker and Barter Exhange Transactions. Stock name, date sold, and proceeds have info but the others are N/A. Additional info has "Cash in Lieu." How should I report it in Turbo tax? Looks like it doesn't accept transactions with no cost and date acquired.  The amount is less than $40.  Thanks.
