This is my first time using the forum so my apologies if I am not doing this correctly.
I live in Johnson County, Indiana and work in Marion County, Indiana. I put the correct county numbers in TurboTax and Turbo Tax calculated county income tax for the county I live in NOT the county I worked in. I ran the return twice with the same incorrect result. I have a letter from Ind Dept of Rev with the error and a bill for the difference. The good news is that I was not charged a penalty but I did not know I had to look up county tax rates to double check TT. I believe this is the same error that the other poster had.
