After hours and hours hunting for a solution, asking the same question as the rest of you with the mysterious wrong "business use percentage" calculation, and reading multiple responses from TT's experts (including the virtually useless "delete vehicle and re-enter" b.s., someone figured out that: IF you answered "NO" you didn't keep track of "personal miles", by changing that to YES, the program resolves the error! OMG. How freaking stupid, but indeed this works, without having to inflate sale price of the disposed vehicle, and other trickery that people have tried out of desperation. I hope TT folks are paying attention to this glitch and FIX IT. Very disappointed 25 year TT user.
