I disagree enetering negative basis results in a gain twice the amount
basis should be entered as 0
ordinary income 9796/9796 (the amt adj is for the capital gain portion
then you need to adjust cost basis on the 1099-B
purchase price
less the adjustment to basis (assume it's a positive number) or add the purchase price and adj to basis as a negative (ex purchase price 26617-6617=20000)
add the ordinary income of 9796
so in my example the revised cost basis would be 29796
the amt adj to line 2k of 6251
you need to access the 6251 worksheet
you will come to a line that says disposition of property
there will be an amount for regular tax. reduce that by 692
then you will see a negative 692 on line 2k of the actual 6251
