For 2022 I am not going to transfer husband's file from 2021.  I will build a completely new file for him, so then it will not be a "split" file.  Fortunately, he only has a W2.  Hopefully, that will disconnect them.  I have used ProSeries (or it's predecessor) since 1988 and efiled for many years.  I have never had this issue before, so it is very disappointing.
