If these were Arizona partnerships the state K-1 would include a page breaking down gains from before and after the 2011 date.  Since they are out-of-state partnerships, I suppose the first question is where were the properties located and does it really make a difference if you are figuring out-of-state tax credit.  But maybe these are just generic REITs with a little gain here and a little gain there.  So are you sure they were all post-2011?  In any case, Arizona doesn't have many people answering the phones, but then they don't have many people auditing returns either.  They can't help you with Lacerte input questions, but neither can I.  It's the same problem faced by anyone with a mutual fund that has capital gain distributions.
