This is one of the popular misconception of trinity and incarnation.
Jesus as Logos (The Word) is divine. He existed in that form for eternity in the Trinity. But the humanity of Christ did NOT exist before incarnation. Humanity of Christ consists of his human soul and body. Humans are made up of soul and body, so when Christ became human, ie., when he took human flesh (physical) and soul (spiritual) form, he raised it to the level of his divinity. This raising was completed to the fullest extent in his resurrection thru his glorified humanity (body and soul).
"At the very instant (of incarnation) that there was flesh, it was the flesh of the Word of God, it was flesh animated with a rational and intellectual soul." - Damascene (De Fide Orth. iii)
Note that God the Father or God the Holy Spirit do NOT have a soul.

Defenders of the Trinity have historically argued that Jesus assumed a soul in the incarnation, not before.
Aquinas deals with exactly this question in the Summa (III.6.3), arguing that the soul of Jesus could not have been created prior to the incarnation, because if that were so it would either indicate that his soul did not need to be united to the Word, or that if it were united, that it was of a different type than our souls:
Origen (Peri Archon i, 7,8; ii, 8) maintained that all souls, amongst which he placed Christ's soul, were created in the beginning. But this is not fitting, if we suppose that it was first of all created, but not at once joined to the Word, since it would follow that this soul once had its proper subsistence without the Word; and thus, since it was assumed by the Word, either the union did not take place in the subsistence, or the pre-existing subsistence of the soul was corrupted. So likewise it is not fitting to suppose that this soul was united to the Word from the beginning, and that it afterwards became incarnate in the womb of the Virgin; for thus His soul would not seem to be of the same nature as ours, which are created at the same time that they are infused into bodies.
In the following article, III.6.4, Aquinas specifically argues that the taking on of flesh and soul happened simultaneously:
Therefore since the soul was not assumed before the flesh, inasmuch as it is against the nature of the soul to be before it is united to the body, so likewise the flesh ought not to have been assumed before the soul, since it is not human flesh before it has a rational soul.
More simply put, the Westminster Shorter Catechism reads:
Q. 22. How did Christ, being the Son of God, become man?
A. Christ, the Son of God, became man, by taking to himself a true body and a reasonable soul, being conceived by the power of the Holy Ghost in the womb of the virgin Mary, and born of her, yet without sin. [emphasis added]
