The guidance in the instructions (below) was steering me towards the non-resident form. (I made a little money while living and working in DE, but made more while living and working in AZ.) However, I guess I need to look at both and see what works. Thanks again.
Part-Year Residents electing to file a non-resident return – This
option may be advantageous if, during the period of non-residency,
you had any income from other states or sources outside of
Delaware.
