Thanks for the reply. I have prepared my Federal and Colorado state returns. I bought the NY State addition and did the work, but the results appear to be disastrous. It seems to be full of mistakes. For example, on form IT-203, the main form, line 32 is supposed to be a copy of line 31, but it is zero. The remaining calculations are based on that number. Also, on one of the worksheets it looks like it should proportion the figures by the percent of time in the state, but it is not. I may be wrong on that. I don't know how to move forward.
