I have a similar problem. I simply answered the TT questions as they came up, and when I entered that I had sold a vehicle, it prompted me to enter what I paid for it 10 yrs ago and what I sold it for. Then, voila, it tells me my line 51. Depreciation allowed or allowable is too large and line 52. AMT depreciation allowed or allowable (what's that??)...are both figures I cannot change.
Please help us someone! Thanks.
