If an undead is concentrating on a spell and a Cleric uses Turn Undead does that undead make a concentration check?

@JeremyECrawford Question! If an undead monster, is concentrating on a spell, and a Cleric uses Turn Undead on that monster…. does that monster make a concentration check? Does it automatically break? Or does it continue concentrating as normal?

I thought Turn Undead essentially operates as a fear spell. Wouldn’t the Undead being forced to leave break his concentration? The tweet you're responding to contains the answer to your question.
