I can't figure out why T-Tax says WI is my free state when I only want/need IL.

I downloaded T-Tax Premier did my Fed and State (Wisconsin) returns and e-filed them.  My daughter from Illinois bought a hard copy of Premier on a disk but ran out of time to do her own returns.

She brought her disk and records to me and I up installed the new copy on my laptop and when the directions asked me to delete my files before loading her copy I did.  The system confirmed this happened and only my return was left behind.

I did her Federal return on her copy just fine but when I tried to start her Illinois return T-Tax said the only free state available was Wisconsin.  

Buy two copies get get two Feds, to Fed e-files and two free "State" returns. Right?
