My W-2 has my current state of residency, starting June 2020. State filing is asking for what i earned in my previous state, which isn't on my W-2. How do I figure wages?

As I'm going through my state filing, I put in the dates of 1/1/20-6/16/20 for my dates as a resident in my previous state. I'm then shown my federal total and asked to enter my state total for "Wages, Salaries, Tips, etc" I'm not sure what I put here, as my W-2 only includes my state earnings in my new state.  Do I subtract the total Federal from what i earned in my new state?
