Welcome home.

I pray for you!
You should start by contacting your nearest parish for enrollment in an RCIA program. RCIA usually starts in August. When you complete RCIA, at the Easter Vigil, you will be baptized if you haven’t already, and be confirmed by the priest.
In the meantime, attend Mass weekly. We just ask you to refrain from the Eucharist.
Baptists believe in believer’s baptism, while Catholics believe in infant baptism. Catholics believe that a validly-ordained priest can transform the bread and wine into the Body and Blood of Christ. There are many differences. However, my fingers have had enough of a work-out today.
You should find a comparison chart on the internet to know all the differences. I highly suggest that you do not ask a Baptist pastor, as we do not know what kind of answer he would give. I’m sure you’ve heard that some Baptist pastors are anti-Catholic and will lie to you about the Catholic faith. I’ve heard of Baptist pastors that told people that the Catholic Church believes in Mary worship, child molestation, etc. You might want to ask a Catholic priest instead if you want more information. A priest wouldn’t lie to you about that.
I also suggest you start praying the rosary daily. As it is often said, people come to Christ through Mary.
You might also want to pray the Liturgy of the Hours, if you have time. I use
