I made a list of projects which should have been set up as tasks.
Is there any way to change this or at least delete the projects so I can do over?
If you're accessing Todoist on the Web, simply hover your mouse over the Project name until a downward pointing arrow appears on the right side of the Project name; click that arrow and you'll be able to delete the Project. Be careful, because once the Project is gone, it's gone!
