Frankly, this makes no sense. I had this same problem. My withholding was on a W2 statement which both the IRS and Minnesota can access. In fact it is more time-consuming for them both to deal with paper forms.
Is this a screwy federal or Minnesota requirement? If so, I would like to know where I can read through this requirement! When I called into Turbotax support, I was promised I would get an email with a list of reasons why electronic submission was not allowed. I still do not have such an email!
