I think I have missed something in your reply (or maybe you answered a different question). I spent some time trying to suss out the solution. I checked out the permission issue and I have permission as per the instructions.
I do not understand the 'split' iTunes library. If it is indeed split, that was not my intention > some kind of mishap/crash or gross misstep on my part. I thought I got things back together by changing iTunes Media folder location to “stephen\music\iTunes” That seemed to right things except finding the “iTunes Library 2018-09-18.itd” was still located in the Desktop folder.
I tried again today to restore my iTunes and only seem to have made things worse.
So, I have to ask again how do I consolidate the files and locate them where they belong. I am contrite and hopeful that I have not trashed my opportunity to make things right in my world. At this point I would even considering uninstalling/re-installing iTunes (saving all files created by iTunes) in an effort to get back to where I was. I do not know if that is even possible.
Sorry for the complications and many thanks to those who try to help people out of darkness.
