there is no 1250 gain from this (5557) it's all ordinary income which should flow to form 4797 part II line 10
you should reach the qbi section of the K-1 since Turbotax does not use the box 20 info for most things and especially not the QBI info.
the amount reported in box 20 for qbi should match line 1 of the k-1 and is entered in the QBI section on the line for ordinary business income/loss
the 4797 recapture is entered on the line for other income/loss
