Jews don’t recognize it as Scripture.
they would know far better than the Catholic church which decided some more than 1500 years later.
And besides, mentioning something as happening does not mean God condones it or commands it.
Scripture recorded that David committed adultery with Bathsheba but it doesn’t mean everyone should commit adultery.
So; it was NOT something that the Apostles preached on and taught; right?
Therefore he made atonement for the dead, that they might be delivered from their sin.
O...K...
At the very heart of the Christian system lies the all-important doctrine of the Atonement. The Apostle Paul, himself an advocate of sound doctrine, in a condensed statement of what the Christian Church believes, said,
For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the Scriptures; And that He was buried, and that He rose again the third day according to the Scriptures (I Corinthians 15:3, 4).

Surely somewhere in Scripture CHRIST can be found praying for DEAD people; can't HE?

Well; I found THIS reference to those who have died...
Luke 16:19-31 Douay-Rheims 1899 American Edition (DRA)
19 There was a certain rich man, who was clothed in purple and fine linen; and feasted sumptuously every day.
20 And there was a certain beggar, named Lazarus, who lay at his gate, full of sores,
21 Desiring to be filled with the crumbs that fell from the rich man's table, and no one did give him; moreover the dogs came, and licked his sores.
22 And it came to pass, that the beggar died, and was carried by the angels into Abraham's bosom. And the rich man also died: and he was buried in hell.
23 And lifting up his eyes when he was in torments, he saw Abraham afar off, and Lazarus in his bosom:
24 And he cried, and said: Father Abraham, have mercy on me, and send Lazarus, that he may dip the tip of his finger in water, to cool my tongue: for I am tormented in this flame.
25 And Abraham said to him: Son, remember that thou didst receive good things in thy lifetime, and likewise Lazareth evil things, but now he is comforted; and thou art tormented.
26 And besides all this, between us and you, there is fixed a great chaos: so that they who would pass from hence to you, cannot, nor from thence come hither.
27 And he said: Then, father, I beseech thee, that thou wouldst send him to my father's house, for I have five brethren,
28 That he may testify unto them, lest they also come into this place of torments.
29 And Abraham said to him: They have Moses and the prophets; let them hear them.
30 But he said: No, father Abraham: but if one went to them from the dead, they will do penance.
31 And he said to him: If they hear not Moses and the prophets, neither will they believe, if one rise again from the dead.
