Cash In Lieu Sales Not Reported in 1099-B - What type of term type to use (uncovered, not recd, unknown)

When entering those CIL transactions into the 1099-B what Sale Section should they be placed under? 

Below are the options that could possibly apply:

1. Long-term basis not reported to IRS (uncovered)
2. Long-term did not receive 1099-B form
3. Unknown term not reported to IRS

These CIL transactions were on my Schwab 1099 tax form in the supplemental section not reported to IRS. 

Thank you very much!
