The income was all earned in Texas while I was a resident of Texas; no New York income was included in that roll over.
Unfortunately you will have to include this distribution as NY sourced if the distribution occurred during the time you were considered an NY part-year resident (regardless of the fact that your original income and 401(k) contributions were made while a resident of TX). Therefore any federally taxable distributions that occurred while a resident of NY, will also be taxed in NY. (If this was a non-taxable Roth conversion for federal income tax purposes, then it will not be considered taxable on your NY state income tax return.)
