I created a document with formulas and made it PW protected. I am now
precluded to open the document to make edits. I am unable to select
"unprotect" and use PW to make edits. I don't know how this can happen on a
document I authored and have ownership. I need this document desperately.

You mean you gave this file a File-Open password? If so, and you
forgot the password, there's very little you can do other than try to
guess the password or pay a service to try to figure out the password.
If you think you remember the password, the first thing to try is
reversing the capitalization you think you used in case Caps Lock was
on when you entered the password.
