How to get "Cost Basis" 1099-B

I have not been able to get a straightforward answer to this here or from my employer or broker. Really hoping to solve this today.

 

Employer sold off stock to pay taxes and I received a 1099-B regarding this. It is a RSU restricted stock unit.

 

Column E "Cost Basis" is empty on the 1099-B.  There is a value in the "FMV per share" column. 

 

How do I get my "Cost Basis"?

 

  • Is it the "FMV per share" multiplied by the number of shares?
  • Is it box 14 "other" on my W2
  • Or is it something else?
