the link worked to create the 2019 directory.  I then closed the file after carrying forward the 2019 file..  Upon trying to re-open i get "You have attempted to create a pre-2015 T1/TP! return.  Profile20 only supports 2015 and later T!/TP1 returns.""

It does have the .20T extension and the file is stored in a directory outside of the normal default (as are all my others from prior years).  I can open those.  I tried by clicking directly on the saved file outside of Profile20 program expecting the file association to work perhaps.  It did not and got same message.  I don't think this program was sufficiently tested before roll-out
