You haven’t told us your Finale version or computer OS.

On a Mac, you would select the chord, and use CMD - up or down arrow to move between the notes. JW Staff Polyphony > Chord Lines will also work, and let you do large sections at once.

Sorry Mike,, I have the latest version of Mac Ventura 13.4

Ok.. so I am an idiot.. since I have never done this action before,, what is CMD?

I think I have it figure out!  :)

CMD means the Command key, the one that looks like a demented highway exit ramp!

As Mike R says the plug-in JW Staff Polyphony will do exactly what you want. It is one of the 8 updated JW plugins included with Finale 27.3. If you don't have 27.3 you can d/l the correct JW plug-in and install it yourself.

Super easy and no plugins needed: just use Speedy Entry, select the note you want to delete, and hit shift-delete. 

Thank you for all of the input/help.  Actually,, I discovered, that if you zoom in to the score like 4 times, and click the eraser icon in the simple entry window, cursor to the note, it will automatically erase the note needed to be erased in the chord.  The issue was that if the cursor wasn't exactly on the note, it would delete the entire chord.  Initially I had been able to do this but it seemed that in zooming out only once or twice, and a sensitive cursor would either do the note or erase the chord.. SO, I decided to try it zooming in even larger and it worked like a charm.. and saved a great deal of time... :)

With the plugin you can remove all of them with one click and you don’t have to be precise. Simple might be okay for one chord or so but not an entire line.
