Bug two moves at the same time instead of two moves in a row

I'm creating a beat-'em-up 2D game. The player moves, runs, jumps, and there's no issue at all. Right now we are developing a sequence of three or four attacks with one key button and here's the issue: the attacks doesn't appear as in sequence, the player just gives all the attacks at the same time when the key button is pressed.
Help! Thanks!

this the code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class XPlayerControl : MonoBehaviour

{
public Rigidbody theRB;
public float jumpForce;
public float moveSpeed;
private int groundMask;
public Transform groundPoint;
private float xAxis;
private float yAxis;

public GameObject colpo;
private int colpoR =-1;
private Vector3 colpoPos;
public float colpoTime = 0.3f;
public float colpoNext = 0.0f;
private int colpoType = 0;


private bool isAttackPressed;
private float attackTipe;
private int isTurbo = 1;
private bool isGrounded;
private Animator anim;
private float attackDelay = 0.3f;
public SpriteRenderer thSR;



// Start is called before the first frame update
void Start()
{
anim = GetComponent<Animator>();
groundMask = 1 << LayerMask.NameToLayer("Ground");
}

// Update is called once per frame
void Update()
{
if (Input.GetButton("Fire3"))
{
isTurbo = 2;
}
else
{
isTurbo = 1;
}
xAxis = -Input.GetAxis("Horizontal");
yAxis = -Input.GetAxis("Vertical");
theRB.velocity = new Vector3(xAxis * moveSpeed*isTurbo, theRB.velocity.y, yAxis * moveSpeed);
//RaycastHit hit;
if (Physics.Raycast(groundPoint.position, Vector3.down, 0.3f, groundMask))
{
isGrounded = true;
anim.SetFloat("moveSpeed", theRB.velocity.magnitude);
if (Input.GetButton("Fire2"))
{
theRB.velocity += new Vector3(0f, jumpForce, 0f);
}
}
else
{
isGrounded = false;
anim.SetFloat("moveSpeed", 100);
}

// COMBAT INPUT
if (Input.GetButton("Fire1"))
{
if (Time.time > colpoNext)
{
colpoNext = Time.time + colpoTime;
theRB.velocity = new Vector3(0, 0, 0);
colpoPos = new Vector3((transform.position.x + 3 * colpoR), transform.position.y, transform.position.z);
Instantiate(colpo, colpoPos, transform.rotation);
attackTipe = 10;
isAttackPressed = true;
// StartCoroutine(colpoPause());
if (Input.GetButton("Fire1") && attackTipe > 9)
{
colpoPos = new Vector3((transform.position.x + 8 * colpoR), transform.position.y, transform.position.z);
Instantiate(colpo, colpoPos, transform.rotation);
attackTipe = 20;
}
}
}
else
{
isAttackPressed = false;
attackTipe = 0;
colpoType = 0;

}

anim.SetBool("isAttack", isAttackPressed);
anim.SetFloat("attack", attackTipe);


if (!thSR.flipX && xAxis > 0)
{
thSR.flipX = true;
colpoR = 1;
}
else if (thSR.flipX && xAxis < 0)
{
thSR.flipX = false;
colpoR = -1;
}



}

IEnumerator colpoPause()
{
yield return new WaitForSeconds(1);


}
