Business & farm

I still can't get the numbers you say.  The questions turbo tax asks is very confusing.  I don't know what numbers to put in which box.  If I put anything in the prior depreciation box it says I have a gain.  Can you please tell me which box to enter which value.  WHat you say makes sense, but turbotax has it all mixed up and confusing!  You can't enter negatives or do the simple math.  See above screen shots in my previous post.  Thank you!
