@Opus 17 thank you so much for such a thorough response. Let me respond to a few things:
Box 17: Originally my Box 17 for NYS was 2,332.86 and WA was 0. Now it is 1,166.43 in both boxes. Presumably because I was only living in NYS for 3 pay periods of 2023, but my company withheld for 6 of them. So its just now the full amount split among the two states even though WA doesn't collect state income tax.
I did work for the same company the entire year, it was my own convenience. I don't know all the particulars of this, but my company is global and across the US. I know my company had to do something on their end to have the company established in WA or something (admittedly I am lacking understanding here, maybe I'm naive about this). I can get more info on that, but based on what you're saying, I did work for the same company throughout 2023 and because I did live there at the beginning of the year it sounds like I am subject to that convenience. Although I did go through the process of filling out the part time residency information through TurboTax
