How difficult is a California 540NR to enter/file if I'm a Colorado resident using TurboTax?

I need to file the California 540NR due to a sale of my mother's house. We already paid the estimated amount during the sale, but now that form needs to be filed for 2021. I assume I have to buy the California State package through TurboTax (correct?). How easy/hard is it to fill out that form with TurboTax? Is there a wizard I can use (as I understand that form normally is somewhat complex) and, if so, how do I get to that wizard while doing my normal tax entry?
