Deductions & credits

I am having the same problem. "Other income taxes" is showing some unidentified number and I have no withholding. I use only estimated taxes to cover my tax bill. My estimated taxes for federal and state are shown correctly on the "estimates" line. My additional problem is that it appears the "other income taxes" number is throwing my Iowa return way off and I see no way to correct the numbers on the Iowa return, Schedule A, Line 4 smart worksheet. Any guidance would be appreciated.
