The sentence `何と言ったら良いか分かりません` means "I don't know what I should say."

But what is the literal translation of this sentence? What is the purpose of
the `か` in `良いか`?

question
grammar translation meaning
Understanding 〜たら良いか〜
you can think of it like:

> What would be right to say? I don't know

何と言ったら良いか分かりません

What to say... / good? / I don't know

the か would supply the question mark in my literal translation above.

か indicates a question. In English, questions in the main clause will be
indicated by inverting the auxiliary before the clause. The addition of か in
Japanese corresponds to that, but in Japanese, か is added regardless of main
or embedded clause.
