Retirement tax questions

I have a question regarding how states handle the COVID distribution pay back.  I understand to pay the CARES Act disbursement back you would go into turbotax and select the button that says I paid it all back, and file an amended return.  When I do this the federal dollars at the top indicate that I would get my taxes related to this disbursement back.  My state return, Iowa, does not change.  What do I have to do to get the state to send me the extra taxes I paid back?
