Hey Tim, thanks for reaching out. Yes, the Kats Heaters # KH11812 is the correct fit for your 2020 Kia Optima with the 2.4L Theta II GDI engine. The conflicting information comes from the fact that Kia used several different engines in the 2020 Optima, and a lot of parts catalogs lump all of the Theta II engines together. That makes it look more confusing than it really is.
If your Optima has the 2.4L Theta II GDI, you're good to go with # KH11812.
