Respect For One’s Stepparent?

I know that it is written that a child has to respect their parents, but does it mention that a child must respect their stepparent as well? And if this is mentioned can someone tell me what is written, and where I can find the direct quote? Also what is the punishment for one disrespecting their stepparent, and wouldn’t it be disrespectful to the parent if their child treats their stepparent in a rude manner? Thanks!
