I sold stock options in a tender offer (cashless exercise). The spread was reported as income on my W-2, but how do I report the short term capital gains in turbotax?

When I try to add the information from my 1099-B in Turbotax, there is no option to identify the capital gain that's not captured on my W-2. It's just a single checkbox regarding whether it was reported or not.
