I'm not sure why you started a duplicate thread. This is not a chat room. It works like a bulletin board.

If you have additional questions on this topic, then please go back to that original thread where a Tax Pro is assisting you, and you can continue the conversation there.
I'll close this one to avoid confusion and redundancy.
