@micks2: I've had a look into this for you, and we don't sell screen protectors for the Galaxy S20 series on our website, although you may have better luck with reputable third party retailers. As an alternative, why not check out the range of cases and covers that we have on offer, for an added layer of protection.
There are lots of good quality tpu screen protectors available from lots if outlets such as zagg to name one.
I personally prefer the feel of glass so I always use the Whitestone Glass Screen Protector as this works well with the fingerprint scanner and has no dead spots due to how it adheres to the display.
