Thank you DavidD66 for your reply. I also looked at this issue a bit further and believe the problem lies in the answer TurboTax writes to boxes 28Y and 28S on the MS state tax form. I followed the approach shown in your screenshot but regardless 100% is posted in boxes 28Y and 28S. The answer in this box is supposed to be the percentage of Missouri income divided by the Federal adjusted gross income. However, as noted it is 100% regardless of how the interview questions are answered so I think this is a bug in TurboTax.
The amounts shown on the Form MO-NRI correctly reflect was was entered on the interview questions but boxes 28Y and 28S show 100%. To me the percentage in these boxes should be based on what is captured in Form MO-NRI.
