After following this thread and getting as frustrated as others, I finally just decided to file after selecting None of the above, as other mentioned to clear the error. I assumed it would file form M1QPEN with zeros. I was a little unsure what MN would do.
But then to my great surprise, when I went to print a copy of my taxes after e-filing, that form wasn't included. It's still in the forms section, but not as one of the forms that printed after filing. So maybe it didn't get transmitted to Minnesota after all.
