How can I add a centered text block on my webpage?

[candicenowrise]

Hi. Im having an issue. I would like to add a centered text block to add some descriptions for the services im providing below that title BATH & HAIRCUT PACKAGE. I would like to have this descriptive text block where I drawed the red square.

but when I click on add column it only lets me add text column with images

I tried to do it withing the code with no luck. Maybe im doing it wrong. Here is the code:

{% if section.settings.divider %}{% endif %}

  {% if section.settings.title != blank %}
    

      ## {{ section.settings.title }}
    

  {% endif %}

  
    {%- assign grid_item_width = 'medium-up--one-third' -%}
    {% case section.blocks.size %}
      {% when 1 %}
        {%- assign grid_item_width = 'medium-up--one-half' -%}
      {% when 2 %}
        {%- assign grid_item_width = 'medium-up--one-half' -%}
      {% when 4 %}
        {%- assign grid_item_width = 'medium-up--one-half' -%}
    {% endcase %}
    {% for block in section.blocks %}
      {% if section.blocks.size == 5 and forloop.index < 3 %}
        {%- assign column_width = 'medium-up--one-half' -%}
      {% else %}
        {%- assign column_width = grid_item_width -%}
      {% endif %}
      

        {% if block.settings.enable_image %}
          

            {% if block.settings.button_link != blank %}
              
            {% endif %}
            {% if block.settings.image != blank %}
              

                {%- assign img_url = block.settings.image | img_url: '1x1' | replace: '_1x1.', '_{width}x.' -%}
                
              

            {% else %}
              {{ 'image' | placeholder_svg_tag: 'placeholder-svg' }}

            {% endif %}
            {% if block.settings.button_link != blank %}
              
            {% endif %}
          

        {% endif %}
        {% if block.settings.title != blank %}
          ### {{ block.settings.title }}
        {% endif %}
        {% if block.settings.text != blank %}
          {{ block.settings.text }}

        {% endif %}
        {% if block.settings.button_label != blank %}
          
            {{ block.settings.button_label }}
          
        {% endif %}
      

    {% endfor %}
  

{% if section.settings.divider %}
{% endif %}
