Illinois return keeps getting rejected. Reject Code IL1040-8600-2

My Illinois state return keeps getting rejected (I’ve tried fixing it four times now) and it gives me Reject Code IL1040-8600-2. I went through everything and my drivers license number is 100 percent accurate. And it got rejected AGAIN. After speaking with a turbo tax specialist for over an hour she told me that I needed to enter an IL PIN. I retrieved my 8 digit IL PIN and entered it while E-Filing and yet it STILL gets rejected. This is the same reason my Illinois state return was rejected last year and it was never resolved. I am at my wits end and I don’t know what to do!
