new client in 2024 - when reviewing 2023 return I see that the entire return is basically incorrect. Most of the errors will be easy to fix but the prior accountant who was only used in 2023 had her as a resident of New Jersey using her 2nd home address as her primary residency and did a nonresident New York return.

She is and always has been a NYC resident. Not sure how to amend it from a NY-203 to a NY-201 in proseries. Will just doing the 201 as a full year resident and nyc full year resident override the non- resident return. I can't get the 201-x to work right now as there is no 201 return.

I think NJ will work just switching the status on the info worksheet. 

Any thoughts? I have a call into NYS but my friend google says just do the 201, explain and mail
