Non-resident State Return

Hello, I am using free file and it is very easy to use and I successfully finished my federal. This year I worked in more than one state but my W2 shows it all going to my resident state. I have started with my non resident state but I don’t see where to input or allocate the income. I get to the screen that says for each type if income it will ask me if it was earned in the non resident state but when I press continue it asks me about income in years prior to 2020 and then moves on to deductions. Can you tell me in which screens I input the monies I earned in the non resident state?

Thanks so much
