Just want to say I am having the same issue. Turbotax has made it impossible to override these boxes or I would fill out the form as the brokerage sent me the 1099B and let the IRS decide how they want to tax me and pay them when they get to it. I should have the option when the information is absolutely not available. I, too, will not be using TurboTax anymore but will buy another product in the future. All of this for a trade worth $28.13 is really not worth it.
