Thanks for your reply.  But I was able to see in the research that Sec. 1250 recapture does not count as ordinary income and is just another form of capital gain taxed at a different rate.  If equipment was sold with ordinary depreciation recapture you could use that as an offset to QBI.  And everything that I have read reinforces what you said about the the negative QBI going on indefinetly.  Thanks reinforcing what I read.
