projectile spawns above the player and not in front of it

this is what my code looks like atm, and i wanna change truerotation to the gameobjects rotation, but changed by(90,0,0): `

public GameObject Capsule;
public Quaternion truerotation;

// Start is called before the first frame update
void Start()
    Capsule = GameObject.Find("Capsule");

// Update is called once per frame
void Update()
{//weird engine bullshit
    truerotation = this.gameObject.transform.rotation;



 if (Input.GetKey("mouse 0"))
       Capsule = Instantiate(Capsule ,this.gameObject.transform.position, truerotation) as GameObject;

Try this:

trueRotation = Quaternion.Euler(90, 0, 0);
