How should I report acceptance of company shares?

I was granted company shares in frames of annual long-term incentive plan. The total cost of shares granted to me is around $26k. At the time of vesting the company sold a portion of shares to pay taxes (about $8k). The total cost of shares granted to me was reported by the company as imputed outcome, both taxes and stock were reflected on my W-2. I also received an equivalent of form 1099-B stating the cost of shares sold to cover taxes as short-term proceed (around $8k) and initial cash paid for the security as a cost (around &8k).

I have not sold any shares this year. My question is should I report the acceptance of the shares in any form additionally to W-2? If yes, what should I report as a proceed (total $26k or 26 minus 8)? What should be reported as a cost?
