Where I can add Cost Type ?

AI generated answer (using internal Slack threads):

In NetSuite, you can add Cost Types in the context of Landed Cost or Standard Costing features. If these features are enabled, you should be able to access the list for Cost Types. For the Cost Estimate Type, it can be set to 'Custom' only on transaction line items, not on the item itself. If you don't see it on sales order or something, you may need to customize the form. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
