I would say that I "messed up," an understatement. My skill set has trouble keeping up with all the changes, etc. these days.

This is my drop down menu. Is this where you wanted me to look?

Right now, I can't think of a eMail. My brain is fried, at this point.
To my knowledge, I have never made a "Smart Folder."
I do have a Time Machine and not been using it. I purchased a plug in hard drive and I have yet to use it (not smart). I knew my eMails were duplicated in my google account and I looked there but nope....
All in all, I anticipate that I may just have to accept the fact that they are "gone."
Thanks for your prompt response. Please let me know me know about the Mailbox/Rebuild option.
