1099-R with Negative Earnings

I received a 2022 1099-R due to an excess contribution in 2021.  The return came before April 18, 2022 but after my 2021 return was already filed. I am older than 59 1/2. The 1099-R has a negative earnings amount as there was a loss.  From other posts I learned to make an amendment to my 2021 returns reflecting the new 1099-R even though it is marked 2022.  Also, from another post I learned to put $0 in box  2A since the amount is negative.  The result is two problems:

 

1) The Federal return shows no change but does show $0 owed.

2) The state (MI) return seems to have not changed at all and still shows the same amount due as at the original filing.

 

Am I doing something wrong?

Do I even need to file the amendments if the change does not impact dollar amounts on the retrurn?
