How can I use a prepared Form 8949 instead of entering a 1099-B?

I received a Form 8949 and a 1099-B prepared using different methods of cost basis reporting, and I would like to use the 8949 instead of entering the 1099-B data and having TurboTax prepare the 8949. How can I do this?  

I am using Wisebanyan and found information about the 8949 vs 1099-B on their website, but I am not sure how to use Form 8949 directly with TurboTax or if it is possible.

Thanks for your help.
