Apparently, there was an old bad cookie or some archival page that was loading when I was using my Edge browser. My Edge browser was up to date with latest edition and updates. After clearing cookies, it worked.
It also worked to use a different browser and an Inprivate tab.
I did not think of using a different browser because I assumed the problem was at the site of the company handling the transfer of payment.
I would like to recommend that file attachments be moved from behind the "more reply options" button. I would have attached screen shots at the very beginning which would have settled the issue even quicker.
I will clear cookies. I have not logged into PayPal for over 5 years or more.
And, I will try an incognito window. First time I have ever had a legitimate constructive suggestion for
employing an inprivate window. I am sure there are many.
I will get back within 24 hours with an update.
Browser. I use a fairly recent Windows Edge. Just checked for updates and was told I have the most recent. I do have Chrome which I have not tried. I was not assuming the problem was inherent to my system, but we will consider all options.
