Same day NSO exercise , no 1099B filed

I exercised some company stock options last year, same day cashless sale. The result of the sale is all ordinary income (0 capital gain/loss) and is reported by my company on my W-2 box 12.

 

The broker did not file a 1099B for this transaction (I guess not required in this case). I'm confused if I need to report the sale on Form 8949 or not, it doesn't change the taxes amount either way. Am I required to file form 8949 for this or will it cause more issues since the transaction is not reported ?
