You are subject to Arizona income tax on all income derived
from Arizona sources. If you are in the state for a temporary
or transitory purpose or did not live in Arizona but received
income from sources within Arizona during 2017, you are
subject to Arizona tax.
File a nonresident return in AZ, and then a resident one in MD (where you also claim the AZ income). MD will give you credit for taxes paid to AZ.
