State tax filing

I did this but there was no other change.  I entered 260 for total days and 50 for days worked in Detroit.  It then showed 210 non working days.  Doing this did not allow me to E-file my state form which I paid for and when I printed out the form it did not show the % of days or the adjusted income.  I think I understand my mistake now due to the poor wording on the tax form but how can I make the change in the online form?  It will only give me access to my federal form and that cant be amended.  How can I update my state and city form that I had to print off because it wouldn't let me efile?  Thanks
