i think i figured it out - had not entered results of sale (primary rez 2 years in last 5). In that section it asked me about depreciation in any year of ownership and looked at last years AMT dep. which said I took $200. Since I entered the info for house sale i eliminated the info I typed in as business property (it classifies as a primary rez vs. business) and returns went back to +$2k versus getting taxed on capital gain (the gain was $75K not the sale price). Thanks for the help
