Welcome to G2G. I see you are already importing people from your GedCom. So you have gone through the matching process and hopefully encountered some already existing profiles.
So I hope your answer 'how to import' is clear.
The thing that might be different from your expectation is that there is no such thing as 'my Wikitree family tree'. There are profiles and connections. You are connected to your parents, they are connected to eachother and their parents etc.
In the end, are all connected. There is also only 1 profile for each person, created by importing one person from the GedCom, or manually creating the profiles. In the past, before my time, it was possible to do mass imports. We are still cleaning up those profiles, which in general do not have sources and include a lot of things we do not like to see on biographies. So some moment it was decided to do a one by one import.
I hated that in the beginning as well, but learned the good part: you get to check all your sources, you can clean up little bits and you can review all weblinks.
This process keeps quality high, at the cost of time and ease. But it is better.
You are maybe not seeing connections in your personal tree view, as you have to make sure you check all the necessary options when importing. Make sure to check the 'is parent' and 'xxx is mother'' options. When importing, start with an early ancestor and work your way up, importing all children only when you have the parents as well.
