You should file a Part-Year Resident return for Arizona, since you only lived there 7 months.
You said that your W-2 showed State Income of $42,393. Does the W-2 show NV or AZ next to this amount? If AZ, then this is your Arizona income, and is what you report on your Arizona return. If NV, then subtract this amount from your Total Wages in Box 1 and that will be your Arizona income amount.
