Income allocation for remote employment

This year, I moved from Maine to Arizona, but I am still working remotely for a company in Maine. I am filing returns for both states. In my Maine filing, I am asked how much of my "nonresident period" income (e.g. income earned while living in AZ) was from Maine sources. Since I work for, and am paid by, a company based in Maine, should I say that 100% of my "nonresident period" income was from Maine sources? This drastically changes the taxes that I would be paying in Maine.
