I was able to get mine finally accepted after multiple rejections. The fix was I needed to go to Turbo Tax's settings page and manually delete the MN portion of my return under a section that had a listing of about 10 or so blue link colored line items with a delete link next to them. I had tried deleting the MN return vis their normal page and also the CRP with no luck until I found the setting pages with that link where I could actually remove the whole MN portion of the return. It did throw one error when ready to file that it was able to auto fix After I did that, I was able to refile WITHOUT using my CRP as that was causing an issue with the name/last name field error flagging it for reject. In both reject instances it took a day and a 1/2 to finally get rejected whereas once I got the original deleted and refiled it was accepted within 2 hours. Good luck!
