1099 B from an insurance demutualization papyment

I received a 1099B from Southern Farm Bureau but boxes 1b and1e are blank. Box 5 is also checked as non-covered security. I am assuming these are payment on shares I received for my membership interest. What do I put in boxes 1b - Date acquired, and 1e - cost or other basis. Also, for the Sale Category breakdown do I put: short term covered, short term non-covered, long term covered, long term non-covered, long term not reported, or unknown holding period?
