Update of record or insert

I have been trying to insert a record form or update the form if the record exists.
I am trying to make sure the form update if user already submitted the form.
I filtered the query by user ID
I added the conditional Step
But every time I try I just insert more and more.
My goal is to update the form or insert the form - Filtering the query by ID-user and ID-Product
