ترجمه - آلمانی-انگلیسی - Wenn ich nur die Zeit zurückdrehen könnte...

'turn back time' instead of 'turn time back'

It's just a matter of choice jollyo, both are correct. I don't think a simple preference justifies a negative vote.

Could you please change it?

Actually this is a rather common phrase, and it is always 'turn back time'.

If I only could turn back time...

I agree.
