How do I change wrong information in my tree

MarileaGosa1

I began my search in Family Search a few days ago . After I added basic information the automatic whatever added a family member with the wrong last name. I tried unsuccesfully to change it or to find a way to replace it without result. I left the site with intention not to return however I want to complete with the correct information so someone else can use the information

What automatic whatever?

I suggest you start with a plethora of articles that you can access via the Help Center. For example:

@MarileaGosa1 Just remember that a product that is quick and easy to learn probably won't do complex things for you that family history requires. FamilySearch's tree is extremely useful, full of ways to document a family history. I would take the time to learn about it.
