Thanks for the quick reply.
I filed and paid the original amounts due back on April 15.
The TurboTax pdf includes the address for Federal, the 1040-V, and the Michigan 4853, all on one page. The Michigan 4853 says to "keep for my records" but has no mailing address. But the online instructions had said I wasn't done if I didn't mail something. So I am confused, still. My intuition says that, since I e-filed, I'm done and just have to wait for refunds now. I'm just not 100% certain.
