Why aren't my Missouri State taxes unable to be filed at this time. I moved from Illinois in the summer. My Illinois taxes went through, not Missouri.

Missouri returns will not be ready for e-filing until 1/23/2025 per Turbotax website. Not sure how your Illinois return was accepted. Federal e-filing is not supposed to open until late January and states do not accept their returns unless the federal is accepted. 

Well, the IL tax filing probably hasn't been "Accepted" yet.

It's just that IL allows e-filing their forms now, even if they are just going to sit on the TTX servers until the Federal forms have been accepted later this month.

@dstrat90    You may not be able to actually e-file those MO forms, until AFTER the IRS and IL forms have been accepted  (or rejected....that's also a possibility).  The 23 Jan date for MO can't be used now since the IRS forms are waiting for IRS action.  You have to wait for their response first. 

Never file in January!.....Always wait until Feb  (March is safer)

I had the same type of error message! Me and my wife work in KS and we filled out the state reciprocity tax credit stuff, but I got this message that Mo wasn't "ready yet". All this despite me filing just today, (the 12th of Feb). I think it's a bug. I just told them I was going to send a check to MO for 82$, (for some reason?). I don't owe MO any money as far as I know. I feel like Turbo Tax used to be easier, and less buggy.
