Well, of the episodes from S17-19 we haven't used, we have:

-The Missing Christmas Decorations

-Santa's Little Engine

-Lost Property

-A Cranky Christmas

-Snow Place Like Home

-Thomas the Babysitter

-Goodbye Sir Topham (which I'm calling until it gets an actual US title)

So any of those will do, I think.
