I passed @da1963 's info along to my investment advisor who followed up with Hines. I got a reply from Hines, which said they just released an updated guide for entering the info on TT yesterday, and sent me a copy. They say that part of what is making this so confusing is that different versions of TT handle it differently (but they do not give any further info about which versions and key differences). Hope this helps a bit.
(Note: I have removed the contacts name. The person at Hines who responded to me has asked that people contact Investor Relations, not him. His role is working with the investment advisors, not the investors.)
