No, there isn't a Christmas song with the initials TBC. There is one with the initials TBHC (The Boar's Head Carol).
The Christmas song with the initials DHFC is "Driving Home for Christmas", recorded by Chris Rea and released in 1986.

I'm not exactly sure. But, the notes you give line up pretty closely to "Have Yourself a Merry Little Christmas." The only notes that would be incorrect is the 4th note -- it should be a C instead of a B -- and the last note, which (if this is the song you are thinking of) would be a D instead of a C.
The Christmas song is a carol.

The Christmas song with the initials Z C is "Zither Carol". The song is a Bohemian/Czech Carol. There are at least two versions of the carol.
