I need help with the California Schedule S, specifically for "income tax liability paid to". I was a CA nonresident for ~2 months (while my full time residence was MD).

I'm stuck on "Schedule S: State postal code - California Nonresidents cannot claim other state tax credit paid to this state/US possession." I selected Maryland in the dropdown menu (since I was a resident there when I worked in California) and then entered the state income tax I paid to Maryland in box A. Something is wrong with the way I filled it out, and I'm not sure how to fix it.
