Ok ...then you must choose the correct section to get the bonus depreciation... just tested it & it works fine but READ every screen or you will miss the election ...

That option does not appear on my screens.  Are you in the individual or business program?  After going in circles again I got it to work.  Had to enter the building information again and then go back and change it to farm...that seemed to work.

Oh sorry ... I am in the SE version ... however you should have the same options.
