Hi Carol... welcome to G2G :)
It looks like you were able to get your own profile up and running as well as profiles for your parents. I assume you probably used the "add father" and "add mother" options which are correct and work super. You can continue in the same way with your grandparents, great grandparents, etc.
Before creating profiles, check to see that they do not already exist on WikiTree, you never know when a cousin of some degree has already been working on your common branches but it's great to find them! When you do, that is where you can link the profiles you have created to the branches that already exist.
Of course you know where you got your information... please make sure to post these "sources" on each profile at the time you create them or add information.
We also have Mentors to help you learn the ropes. Mine was invaluable to me!
As always, you can ask for advice here in G2G.
Cheers!
