State tax filing

I am not trying to deduct income from my Federal tax return. I am rendered at my State taxes (PA) and since TT knows I am part-year resident, he gives me the option to adjust my federal income for my State taxes (please see screenshot below - this is thr State taxes step not federal).

I am trying to deduct 1$ from part-year resident PA state return. I earned this 1$ after I moved overseas (no longer resident of PA state). That's why I am trying to deduct in my State return this 1$ from my Regular interest income.

Please look at the screenshot below:

I don't know why but TT only lets me adjust the US government interest and not the Regular interest of 67$. I need to remove the 1$ from the $67 of Regular interest but TT won't even allows me to do that.

I think it is a bug. Please help me, how can I adjust my Regular interest here?
