Indiana recomputed Tax Due Form IT-40RNR

I paid for Turbo Tax Indiana and filed electronically, also at cost to Indiana.  Part of my wife's income was earned in Indiana, but we are full time Michigan residents.  Indiana is supposed to have tax reciprocity with Michigan.

My refund was supposed to be $923.00 but Indiana refunded only $588.00.

 

Indiana sent a letter stating that $335.00 was due to Porter County Tax.   I believe the Letter from Indiana Dept. of Revenue is incorrect and that she should receive the Porter County Tax as a refund.  

 

What should be included in the appeal to in.gov/dor/legal-resources/appeals to obtain her full refund?  

 

If this is an error in the Turbo Tax Indiana Form IT-40RNR, please correct and advise.

 

Thanks,
