in step mode you'll come to a page that says 'we need some information about your 199a income)
the 751/liine 20ab amount/ is entered on the other income line and also the line below which says "total ordinary form 4797 gain (loss) included above" however checking learn more says this related to 4797 gain/losses reported on line 11 of the k-1.
i tried both ways leaving the 4797 line blank and then entering the amount. there was no effect
