I need to attach a K-1 to my state tax return (Michigan) so I can prove the flow through entity taxes paid. Can I, and how do I, add an attachment if I E-File?

if that k-1 must be sent since there is no way to attach it as pdf to an efile. but the state return should have the ability to enter state k-1 info from your actual k-1. in illinois the tax withheld is described as pass thru entity credit amd entering it on the state k-1 treats it as a tax payment

Thanks.

Yes, I entered the K-1 info into the state return...but Michigan requires the attached K-1 for verification. So it seems I have to mail in my state taxes now. Seems archaic for TurboTax not to have solved the issue of allowing attachments by now.
