Thank you for your reply.  As you can discern, I am struggling with the software.  My thinking is that the one rental property which generates QBI should be on one Schedule E, and the one that doesn't should be on another Schedule E.  The software will not let me delete any properties off Schedule E.  Combining the two on one Schedule E seems to require that all of the income, from both properties, will either be deemed QBI or none of the income will be deemed QBI.  I gather the inability to delete a property from Schedule E arises because I reported both rental properties on one Schedule E in 2018.  Thus my problem.
