Can't e-file MN Schedule M1W duplicate W2

[russl]

My wife and I own a business where we are each paid the same amount on our W2s with the same deductions. We've been doing it this way for at least 10 years. Turbotax flags a potential duplicate every time we do the entry, which I appreciate, but allows me to continue and it's never been an issue. 

This year when I go to e-file it pops up a "Check this entry" error flagging the MN form M1W for duplicate information. The form correctly shows that one of the W2s is for me and the other for my spouse so it is correct. I tried going back to forms the income entry and changing the payer name slightly for one of them just to see if that would move it along but it must be using the tax ID and amounts to flag the duplicate.

What do I do to move it through?

Raise the income in box 1 by $1 for one of the forms W2.

I thought that would work for sure... but no luck. Even with a different amount it thinks it's a dupe.

On the W2 that you changed the box 1 amount also change the box 16 state wages amount to match.

Unfortunately, that doesn't work either. The first thing I tried was changing only box 16. That was what showed up in the form, so it was different than the other one on the form, but it still called it a dupe. So I went back and changed box 1 in addition to box 16 but still no go.
