I am not sure this is the right place to ask this question but assuming any traveler might have come across this situation/have information,requesting to please guide.

I had arrived USA 2 months before on B1/B2 visa.As I-94 forms are now paperless, i did not receive one at the time of arrival at USA airport. But i can see details of same on cbs.gov website. In paperless I-94, where do we need to return the form / do we need to return the form when I leave USA? I checked website but it had information regarding the case when paper I-94 is received.
