Well I don't have that exact screen (perhaps that is the online version?) but to dispose of the vehicle the info requested flows into the Car & Truck worksheet which has tracked cost, depreciation, etc since initial use so most of the fields are prepopulated. My problem is that somewhere Turbotax has calculated the business portion of the basis but does not show this and appears to have substituted 0 thus triggering the error that past depreciation has exceeded it and is thus not allowed which reverses 20 years of past depreciation into a gain!
I can override the cost basis on Form 4797but this does not correct the error on the worksheet and creates an override error so I can't field electronically. I thik I still need to find where and how the business basis was computed and fix that if possible.
