It means that the purchase date and cost basis of that particular security  you sold within 2018 is unknown to Fidelity.  You need to provide that information from your own records.

Does it mean that it is unknown to Fidelity or that it just did not make it to the 1099-B?

TurboTax won't let me put in unknown?  What amount do I put in the cost basis box?
