From your description, seems like you are missing client_id parameter,

Here is the guide for authorization code with pkce (which you would use, if you have selected application type as single page application in Okta). For example

curl --request POST \
  --url https://${yourOktaDomain}/oauth2/v1/token \
  --header 'accept: application/json' \
  --header 'cache-control: no-cache' \
  --header 'content-type: application/x-www-form-urlencoded' \
  --data 'grant_type=authorization_code&client_id=0oabygpxgk9lXaMgF0h7&redirect_uri=yourApp%3A%2Fcallback&code=CKA9Utz2GkWlsrmnqehz&code_verifier=M25iVXpKU3puUjFaYWg3T1NDTDQtcW1ROUY5YXlwalNoc0hhakxifmZHag'
