Necessity for multiple state return

Hello community!

 

     I live in NJ but have worked in NY for the entirety of 2021.  In the past, I have had to file both NJ and NY state returns, and everything works out in the end.  I used the TurboTax application for my 2021 return instead of the online version this year, and as I was entering Federal and going to state, Turbotax told me it would let me know if more than one state return is required.

 

     Turbotax did not say at any point I needed more than one state, so I completed federal and NJ state (my state of residence) with the info from my W2 and have e-filed them.  My questions are:

1. Do I need to file a New York state tax return like in years past?

2. If so, do I need to amend my federal and NJ state if I file NY after Federal and NJ have been submitted?

 

I'm so confused, any help would be appreciated.  Thanks!
