8949 reporting for abandoned security

I had a long term security position in my brokerage account (about 6 years old) that I wanted to abandon so I did a procedure with the brokerage firm to take this non-tradable stock out of my account at a price of zero, they sent me a trade confirmation at 0 for it but they do not include it in the 1099 so it's up to me to report it as I see fit. Two questions:

 

1) I am confused whether to report it under code E or F

2)  Should I put abandoned in the security description or do anything else to say it's an abandoned security
