Simplifying TextChange Event

Good morning to all, i was just wondering if it's possible to simplify these codes? i have MULTIPLE textboxes with the same textchange event

    private void txtOvertimeHours_TextChanged(object sender, EventArgs e)
    {
        if (txtOvertimeHours.Text.Length <= 0 || 
            txtOvertimeHours.Text == null || 
            txtOvertimeHours.Text == "0.00" || 
            txtOvertimeHours.Text == "0" || 
            txtOvertimeHours.Text == "0.0")
        {
            txtOvertimeHours.Text = "0.00";
        }

    }

    private void txtAllowance_TextChanged(object sender, EventArgs e)
    {
        if (txtAllowance.Text.Length <= 0 ||
            txtAllowance.Text == null ||
            txtAllowance.Text == "0.00" ||
            txtAllowance.Text == "0" ||
            txtAllowance.Text == "0.0")
        {
            txtAllowance.Text = "0.00";
        }
    }

//and so on
