Can't find HZD remaster upgrade

HZD came with my PS4 when I bought it. When I bought a PS5 in Feb. 2024, HZD was the first game I ported over. When I go to try to get the upgrade in the playstore it says I have to pay the whole $50 USD. I saw from someone else that you have to add it to thr cart first, but when I go to the cart it still says $50. Could I just not have access to the upgrade because HZD came with my PS4? I'm logged in to the same PSN account and everything, so I know it's not that. Thanks!

Edit: I figured it out. The game is owned by my husband's PS account, and if I go to the PS store from his account the $10 upgrade is available. The thought dawned on me that he was the one who set up the PS4, and I didn't get my own PS account added until later. Thanks to everyone who tried to help!! Saving this for Google to pull up.
