Mike,
Please check this tutorial for adding an existing project as new project to TFS :
https://msdn.microsoft.com/en-us/library/ms181277(v=vs.90).aspx
I suggest you also check with development/TFS related forums like stackoverflow.com for better support as this is a TFS related query.
Hope this helps. Let us know if you have any questions.
