Taxpayer did not live in Illinois in 2019; spouse was a part-year resident of Illinois.  I've entered dates of residency correct on Federal Information Worksheet. However, IL Schedule NR requires dates of Illinois residency for Taxpayer, even though he was not a resident in 2019. ProSeries will not allow me to leave the fields blank or enter "N/A". The next column showed that the Taxpayer lived in another state from 1/1/19-12/31/2019, but the program still requires a date for Illinois. I tried to enter 1/1/19-1/1/2019, but then the error message says the two fields cannot be the same date. Any way to resolve this? Must I just paper file to fix ProSeries bug?
