@laceysharpe let's try and simplify this.
1) you were a resident of CA until 9/1/22. You will file as a 'part time resident' and report all your income received in CA throught 8/31/22.
2) you worked in MD for two weeks and the income for those two weeks was assigned to that state. You will file as a 'non resident' of MD and report those two weeks of income.
3) you were a resident of NC post 8.31.22. You will file as a 'part time resident' and report all your income received in NC. (That will exclude the two weeks in MD).
4) if your W-2 has withholdings in VA, you will file as a 'non-resident' and get any withholdings back.
There is no overlap in income the way I laid this out. Presumably you are stating your W-2 shows income in 3 these three states: CA prior to 9.1; NC after 8.31 (except for the two weeks in MD which is separate).
I can't imagine the sign on bonus was reported to two states - that would mean if you summed up the state income from each state (line 16 of the W-2) it exceeds the federal income reported (box 1 of the W-2). Please clarify whether or not that is the case.
