How to fix 404 errors appearing on Google from deleted products?

Hello, I got a console alert for a lot of 404 errors but have some questions so I understand. The products are on the website. I noticed that google has a slightly differ it has (web-pixels-manager@x.x.xx/sandbox…) I put xxx instead of number for privacy.

Others are products where I may have changed the name and products I put together to make a set and deleted old one but it still must be appearing in google. I checked my google products via shopify app and they are not there. So the URL doesn’t exist anymore but google is seeing it. I just deleted it from shopify, is there anyway in shopify I can check why these product links are still active.
