CA Schedule S Line 7

I'm trying to figure out what to enter for CA's Schedule S ("Other State Tax Credit"), Line 7 "Income tax liability paid to other state." In my case, my other (resident) state is OR. Does anyone know if Line 7 is supposed to include my tax liability before or after my state's refundable credits? (In the case of OR, refundable credits include things like 529 contribution credit.) My tax person last year used the number after standard credits, and TurboTax seems to default to the number after refundable credits are included as well (which is a big difference for me!).
