ps glitch putting © before title but this is NOT showing up in finder and NOT what I want

It’s not unusual or new. You may have noticed that for many years, the document title bar contains at least 7 different types of information, 6 of which have never been expected to be part of the filename.

What is found in a typical document tab are, as seen from left to right:

Copyright Status metadata field is set to Copyrighted

Filename

Current view magnification

Selected layer

Color mode

Bit depth

Document contains unsaved changes (*)

Makes no sense.

So, going by the above list which is not in any way new, we know that having non-filename info in the document tab is not some strange new thing, so it does make sense. The real question here is about what the © at the beginning is for.

The © means that in File > File Info, the Copyright Status metadata field is set to Copyrighted.

This may seem trivial, but in some legal jurisdictions such as the USA, whether or not a copyright notice is saved with the file can mean the difference between whether or not a court will award you a significant financial remedy for a copyright infringement. For those wanting to ensure a maximum possible financial remedy, making sure that © is in the document tab could mean real money, so for them it’s a nice reminder. But of course it works best if the Copyright Notice field is also filled out, according to the requirements of your legal jurisdiction.

That means the image has been marked as copyrighted in the file's metadata. Look in File > File Info.

Any image is automatically copyrighted to the creator from the moment it's created, so a copyright symbol is strictly speaking redundant. Copyright always applies, unless a Creative Commons license has been imposed by the author. That overrules and releases the copyright, according to the specific CC terms.
