my Grand Rapids Mi. form cf1040 still says do not file ?

Michigan Form CF-1040 cannot be electronically filed and would need to be mailed in per the forms availability list.

If you actually have the form and it says do not file across the form, you may need to update your program to ensure all of the updates are loaded.

This can be done by logging into your desktop product.  Select Online in the menu on the top, and then select Check for Updates.

If that does not update your program, you can also manually update your program.

If you are using TurboTax Online, the program should be automatically updated.  But if you are still seeing the do not file message, try clearing your cache and see if that helps.
