Taxpayer has no remaining basis in S Corp investment. Current year loss reported on K-1 carries to form 8582 and a portion gets allowed (other investments on form 8582 mix of loss and income). If I try a form 6198 (which is incorrect becase he is at risk) I can get the loss disallowed but still it gets carried to the form 8582 and because of other investments a portion gets allowed. Once a portion is  allowed on form 8582 it gets  carried to schedule E-2 and allowed as a deduction. If I eliminate the loss on K-1
