Michigan Department of Treasury confiscated most of my Michigan refund stating that I needed to include a copy of my North Dakota income tax return to verify the income from outside of Michigan, as well as the income tax paid to North Dakota.
Nowhere in TurboTax is there any mention of including a copy of my North Dakota return with my Michigan return.
As a result, Michigan is now holding $1,559 of my $1,869 refund until this matter is resolved. I've sent what they asked for, but it appears they are very slow in resolving these situations.
I suggest TurboTax brush up on Michigan (and other states) requirements regarding income attributable to another state.
