There is a sentence
To where are you going to go?
Is this one correct? Or should I write
Where are you going to go to?
Thanks in advance

You could say "Where are you going to go?" (To isn't strictly necessary) or even "Where are you going?" if the context makes it clear that a future journey is being discussed.
