My client lived in Iowa all of 2021.   He married a girl from Illinois in June 2021, so she is a part resident of Iowa & Illinois.  she has Illinois income & Iowa income.   When I filed the original return, I must have hit a wrong button & told the NR form that the husband was a resident in Illinois too.  I read in the instructions that in Illinois, I have to either have all of their income in Illinois or file them separately.  So I am trying to file an amended Illinois return separately.  I did the IL 1040X for the husband with zero income.  My question is, How do I file the wife separately in the original federal file?  I don't see any place to tell the program who's amended return this is- it just assumes that I am preparing the husband's separate return.  What am I missing?
