The QBI calculation performed by Turbotax on my return is wrong, producing a number much higher than it should. How can I see the details of the calculation?

2 K1's = 57,054, Sch C = 47, Sch E (rental) = 5,390, 1/2 of SE tax = 2,290. This should give QBI= 12,040, but Turbotax says it is $ 16,977 !! Why?
