TurboTaxToddL:  That worked!  Many thanks!  I am in your debt.  Follow-up question:  My K-1 has entries in both Box 1 and Box 2.  TT says to therefore enter this as two different K-1's.  But I have no idea how to segregate the Box 3-20 items that are associated with Box 1 income (business) and Box 2 (Rental).  And if I just enter all the same info twice, I get hit with double the tax.  Should I ignore the TT advice to enter as two K-1's, or is there a way to segregate the remaining boxes and associate some entries with Box 1 and some with Box 2?   Any advice appreciated.

First, you do have to enter this as two different K-1s. I believe it works fine for one K-1 to report Box 1 income and the other to report Box 2 income and the remaining K-1 items. There is a small chance there might be "conflicts". Update this comment with details if that happens.

TurboTaxToddL:  Thanks again!  This also worked.  For the second K-1 (1065) I re-entered all the same information as the first K-1 for Parts I & II, items A - M.  Then for Part III of the K-1, I only entered the data from Box 2, and did not enter any info from Box 1 or from Boxes 3 - 20.  The double-hit on taxes is no longer occurring, so I think (hope) I'm now good to go.  I owe you one.

My pleasure!

I also have multiple entries for line 20Z (as well as 20AA), but when I leave the field blank as you indicated, I don't get a prompt to enter the details.  Is it okay to enter the information like I've done below:
