Hello, I bought Rocket League many years ago on PC (Steam), I also got Rocket League last year on Xbox, both account have different items/progress/badges.
When I logged into PC version it asked me to use an Epic Games ID, which I do have, I logged in, then it asked me if it was going to be my primary account, I want to ask if there's a way to "merge" my items/badges all that from both accounts, I really don't want to lose my already paid for unlocked content.

Yes, though functionality may be limited right now, you can link your platform accounts at https://www.rocketleague.com/activate/. Keep in mind that the primary account will determine which account's progress is used.
