So there isn’t an official translation but many different ones used?
Yes and no. There is no one “Catholic Version”, but the Church does mandate the use of a particular translation for a particular purpose.
The Vatican has decided that every country should use only one translation of the Bible in the mass, but left the bishops of each country responsible for deciding which translation to use. For instance, the bishops of the US have chosen the New American Bible (NAB) as the source of the scripture readings for the mass. In Canada they use the NRSV-CE. In the Caribbean it’s the RSV-2ndCE. I think it the rest of the English-speaking world they use the Jerusalem Bible.
The Catechism of the the Catholic Church uses the RSV and the NRSV when it quotes from the Bible.
On top of that, there are many different translations of the Bible that are not used in mass but that have been approved for personal study. In addition to those mentioned above there are the Douay-Rheims, Confraternity Bible, Knox Bible, New Jerusalem Bible, Christian Community Bible, etc.
There are also many Catholic editions approved for personal study of popular or Protestant Bibles such as the Living Bible, RSV, and NRSV (already mentioned above).
There is no Catholic edition for the NIV, ESV, KJV, NASB, NLV, TNIV, etc.
Cheers.
