Hi @evamoondesigns ,
To access your carrier-calculated rates for different carriers, there are 3 options:
- Add this feature for an additional $20/month on your current Shopify plan
- Choose a yearly subscription for your current Shopify plan, with which you can get this option for free.
- Upgrade your plan to Advanced Shopify Plan
Once you choose any of these, you can contact Shopify support to enable it in your store
