		];
		$comment = Comment::create($values);
		// $comment->set('field_comment_category', 'writer');
		// Last, we actually need to save the comment to the database.
		$comment->save(); 

If you have added any other fields in comment then you can use as below code format

$comment->set('field_comment_category', 'writer');

In given example I have added a field comment_category
