I didn't do anything but plug it in and download the Alexa App. You folks gave me an idea what the problem is though. I'm not a big Echo user - use it mostly to set timers and control lights. I wasn't very clear about it not shutting up.
I don't use my phone for anything but a grocery list - I play games and read news on my computer, not the phone. But i THINK i may have paired the phone with the bluetooth on my desktop, not knowing what it would do. It came up and I just followed the screem prompts. I bet that's what's happening, it's connecting to my desktop via the bluetooth.
Not sure how to disable that but I'll look around and see if I can figure it out.
Thank you much for the help!!
