State tax filing

Perhaps a little clarity.  I was originally hired to work out of NY City and have filled 100% of my income there every year since 2015.  However, over time I transitioned to a work from home model.  In 2019 I filled all my income as earned in NY because I was commuting in 3 days a week and the other 2 were more convenience.  

 

However, by 2020 I have stopped commuting in and worked everyday from home - Pre COVID19 decision.  In April 2020 I was made redundant and started claiming NY Unemployment because thats where I had been filing my state taxes. 

 

Therefore I believe I do need to allocate the portion of my earnings from my employment through end of March plus my unemployment income from NY as 100% NY income.  However, When I received my severance in June it was not tied to any duties I had to perform in NY and I no longer spent anytime in NY so I wanted to allocate this portion to NJ where I live.

 

This will reduce my state tax by a little but I do not want to do this if it will possibly raise a red flag or is a grey area, only if its clearly the right way of reporting.  Especially as I am now dependent on NY unemployment.
