I found that my store was showing the same price for all upsells as the product itself. 
So if the product was $1300.00, the upsell product was $1300.00. 

After researching and finding an article at: 
https://magento.stackexchange.com/questions/217427/magento-2-upsell-product-list-showing-same-price-as-of-product 

I did a search for the string: "priceBoxes" on the server in the app folder. 

The page that showed was:
app/code/Lof/HidePrice/view/frontend/templates/product/view/form.phtml

So I changed line 125 from: 
var priceBoxes = $('[data-role=priceBox]');
to: 
var priceBoxes = $('.product-info-price [data-role=priceBox]');

It appears this is working now. 
Is there any other code I should change that might affect the site?
