Where do I enter items that go to Form 8949, Part II, Box F? Where do I go in TurboTax to do this?

I just need to know where in TurboTax online to enter information that goes to Form 8949, Part 2, Box F? An accountant told me how to write off my unrecovered basis in a business sale. He said it goes on on 8949, Part II, Box F. Please be detailed on how I get there online. Thank you
