Filed state taxes wrong

I filed my state taxes wrong. 

I am a resident of Illinois but made all my money in 2021 in Colorado. I did not make any money in Illinois. I filed in both states but I needed to just file in Colorado. I accidentally submitted my state taxes to both - the Colorado one was accepted and the Illinois one was rejected. How do I delete my state taxes in Illinois?

If you are an IL resident then you must report all your income from all sources  to IL  and also file a non resident CO return.  If the IL return was rejected then it was not filed ... you should fix the rejection and resubmit it or paper file it.

I am not sure how to fix the rejection. The code says IL1040-8100-1.

Also - it is saying I owe money in Illinois but that shouldn't be right. I am paying state taxes to CO this year.
