During the e-file process when I click on "Transmit Returns Now" I get a Turbotax error message that says: "We can't file your return because we are unable to locate the attachment at . Please go back and re-attach it. Then try e-filing again".
This error is happening for my MN State tax return. For MN I am filing "Resident" but I have two other non-resident state tax returns - WI and MI. Both of these as well as the Federal return were transmitted successfully.
