Do I need a pen name if I publish under my real name?
I publish under my real name. Why are you making me create a Pen Name?
On Booksprout, you can create multiple author profiles based on the names you publish your books under. If you're using your real name, that's great! You can create a Pen Name using your real name, it's not an issue at all. If you publish under various names, you'll want to add those separately to Booksprout.
