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.
