I got this same exact error message today, i'll wait and refile MN again on probably 2/1 to be safe. This is my first year in MN and I was like "lord what did I enter in wrong?" This is the first time i've ever been rejected. Nothing I can do for right now but wait. Funny thing is the link that is on this posting shows the file (MN Individual - Form M1) is ready.. so idk
