Yes, I think you would, because although you were baptized, you haven’t received your First Eucharist so you’d need preparation for that, as well as your confirmation. But no, you wouldn’t be baptized again.
Technically, RCIA is for the unbaptised. It’s not a class, it’s a series of rites. None of those rites would apply to you since you are already Catholic.
it is up to your pastor, make an appointment and share your story so he can give you preparation that you need and works best for you. There is a provision in the RCIA for baptized but uncatechized adults. That can be people like you who were raised in a non-Catholic denomination and have good basic Christian formation, but are lacking in knowledge of specifically Catholic doctrine and practice, particularly on Eucharist and the other sacraments, or who bring a lot of questions to resolve. It could also cover people who were baptized but have had no religious upbrining to speak of and are essentially covering the same ground as the unbaptized.
