I'm having the same issue and I deleted the software by accident without realizing that I had thrown away the CD-rom. So now I'm out of luck and can't even open anything. What can you do for us Turbo Tax?

If you have some form of proof that you purchased the product (e.g., a receipt), then contact Support (link in the previous comment).
