I've been following a youtube tutorial and when I followed and rewrote the input it worked but Unity kept reading input when there was none. Video Link to tutorial: https://www.youtube.com/watch?v=_Pm16a18zy8&list=PLLf84Zj7U26kfPQ00JVI2nIoozuPkykDX

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

public class PlayerController : MonoBehaviour
{
    public float moveSpeed;
    public bool isMoving;

    private Vector2 input;

    private void Update()
    {
        if (!isMoving)
        {
            input.x = Input.GetAxisRaw("Horizontal");
            input.y = Input.GetAxisRaw("Vertical");

            if (input != Vector2.zero)
            {
                print(Vector2.right   "|"   Vector2.left   "|"   Vector2.up   "|"   Vector2.down);
                var targetPos = transform.position;
                targetPos.x  = input.x;
                targetPos.y  = input.y;

                StartCoroutine(Move(targetPos));
            }
        }
    }

    IEnumerator Move(Vector3 targetPos)
    {
        isMoving = true;

        while((targetPos - transform.position).sqrMagnitude > Mathf.Epsilon)
        {
            transform.position = Vector3.MoveTowards(transform.position, targetPos, moveSpeed * Time.deltaTime);
            yield return null;
        }
        transform.position = targetPos;

        isMoving = false;
    }
}

I just made a test project with this script and it seems to work as intended for me. Feel free to elaborate but if you mean that it reads input for a few frames after you stop input until the character stops, then that is a product of how you have movement in a coroutine. That style of movement would work fine for a point and click or something where you want to move the character to a specific point on the screen but for input it will feel laggy. I would suggest either adding a rigidbody2D to the player and moving it by adjusting its velocity or by directly changing the transform.position just not in a coroutine, but if your issue is something else feel free to give me more info.

Most commonly this turns out to be caused by some type of input device being connected that you didn't intend to be reading input from - e.g. a game controller, flight stick, driving wheel or similar. Try disconnecting nonessential USB devices and see if the input readings go away.
