@NCperson , thanks a lot for helping with this. Thanks, @Critter-3 . I appreciate the help from you guys.
I lived in NJ for a continuous 48 days period and for those 48 days my work location for the company A was in NJ. I had a home in NJ and got an NJ state driver's license within the period. Then, on the 49th day I moved to CA and that was my start day with the company B, and my work location for the company B, from the first day with them.
However, company A sent my final paycheck on the 52nd day. All the money earned in this paycheck was for the work I did in NJ while living in NJ (and maybe the PTOs payoff that were accrued in IL too) and in this paycheck they withheld state taxes for NJ only. However, I had already started living in CA by then but my new residence address wasn't updated in their system by then, so they had no reason to hold taxes for CA. Now, I am not sure if the final paycheck amount should be taxed in CA too, as the day when I got that money I was actually living in CA, though I earned that while working and living in NJ.
Please let me know if you need any further details. I am not sharing the exact dates to maintain some anonymity but if the exact dates really matter I can share those as well.
