After you file

@bgkr - if the IRS already made all the adjustments to the Federal return, then you would only need to amend Michigan

 

any idea why the IRA adjusted the AGI? what are the circumstances of your HSA....it is just unusual..... was the $650 on your W-2 (box 12 COde W) AND you entered that number elsewhere in turbo tax so that it also ended up on Line 10 for Form 1040?  Just let's be sure the IRS adjustment is correct before fiddling with Michigan,
