God is giving you grace. I know that Baptists have a large amount of respect for the Holy Bible. You should know that the Catholic Church preaches love for God’s infallible Word. Also, I hope you looked at that article which shows how TULIP can be similar to Catholicism in some respects.
It would take a long time to go through all those doctrines. Just for one, we believe Mary is the Queen of Heaven. In the Old Testament, all the Kings of Israel’s mothers were the Queen, not the wife. And since Jesus is the true King of Israel (Son of David), and the King of Heaven, we say Mary, His mother, is the true Queen of Heaven.
As for transubstantiation, let’s look once more at John 6:53-63:
“The Jews therefore strove among themselves, saying: How can this man give us his flesh to eat? Then Jesus said to them: Amen, amen I say unto you: Except you eat the flesh of the Son of man, and drink his blood, you shall not have life in you. He that
eateth my flesh, and
drinketh my blood, hath everlasting life: and I will raise him up in the last day. For
my flesh is meat indeed: and
my blood is drink indeed. He that eateth my flesh, and drinketh my blood, abideth in me, and I in him.”
The word used for “eat” here is “trogon”, which is the most literal word for eat you can use.
However, the Jews didn’t believe. “This saying is hard, and who can hear it? But Jesus, knowing in himself, that his disciples murmured at this, said to them: Doth this scandalize you?” Jesus asks us if we will allow this doctrine to scandalize us.
“If then you shall see the Son of man ascend up where he was before?” Jesus uses his divinity to prove what He says.
“It is the spirit that quickeneth: the flesh profiteth nothing.” The Jews could only apprehend things in a carnal way. They couldn’t understand having Jesus’ body and blood in a sacramental way.
“The words that I have spoken to you, are spirit and life.” Jesus in the Most Holy Eucharist gives us grace and life.
Afterwards, many of His disciples left, because they couldn’t accept His teaching on the Holy Eucharist. But He did not stop them. If this was just a parable, why would it upset so many people? And why wouldn’t he clear things up, like in every single other instance of misunderstanding? Not only that, if Jesus was using a metaphor, it would be referring to a Hebrew idiom about brutal war, which makes no sense in the context. (cf. Deut 32:42 and Ezek 39:17-18)

I didn’t convert from any other religion, but was a practical atheist. All the best.
