It would not allow me to file my return because my Professional Educator's License number was not 9 digits. The state of Illinois issues 7 digit PEL numbers. If it will not allow me to e-file without 9 digits, there should be an onscreen prompt on how to fix this (ie: if your PEL is less than 9 digits, add 0s in front of the number until it is 9 digits). I had to dig through google searches until finding a post on what I was supposed to do and even now, I am worried my return will get flagged or rejected because I put extra 0s in front.
