Hi!
To answer your questions: I wound up getting a decent refund (or will be) on my 2020 and 2021 taxes, no dependents or spouse, and I currently still contribute to a pension and 401k at my old job and am about to enroll in a 401k at my new job.
Since the overlap is only about 2 months, it may just be worth filing the new W4 as if it’s my sole job, unless you see something up there that hints otherwise.
