Your are absolutely wrong. If one reports the 4th quarter (not the first quarter) payment as made on 01/18/22 ( the correct date dictated by the federal and IL govt) but Turbo Tax says the due date 01/17/22 then you are one day late and the program calculates a penalty. If TurboTax had the due date as 01/19/22, that would be incorrect as well.
