I just want to know what this means, did i not fill out all of the form correctly, do i just wait longer, how long do i wait? my illinois return is important to me for a bill
The IRS did not begin to accept or process 2020 returns until February 12; a state e-file could not be accepted until the federal e-file was accepted, so not sure why you think it has been such a long time---it has been less than three weeks. And...unfortunately, IL is not known for being very fast to issue refunds. If the state wants any additional information from you they will send a letter.
Only IL can advise you as to the reason, as it does not notify TT. But it could just be a generic "we're still working on it" message. Also see this, especially # 9, What if I am counting on my refund for something important?

@mattosiris How long did it end up taking for you to receive it? My status says the same thing.
