Your screen shot of the page you said was for submitting a help request is not the page your link took me to.

I stumbled on the download yesterday.
And though it was shown as the 2019 version, it loaded the 2020 version.

If anyone else needs to reload the 2020 app this is the site to get it -
1. Download the latest version of Kaspersky Internet Security 2020 via direct link: https://box.kaspersky.com/f/756127006190481ab3ca/?dl=1
