<<But i think it is referring to the current 2019 return.>>
That's what I would assume too.
BTW, if you moved into DE in 2019, you should be doing a part-year resident return for both DE and the state you left.
In the year of a permanent move, you're a part-year resident of each state for tax purposes.
