How to remove a financial type from profile is already created and data is submitted?
I'm not 100% clear on your question but I think it is one of the following:


The [x]CiviContribute option in the screenshot above is automatically checked if you add a profile to a Contribution page. If you remove the profile from all Contribution pages, that option will disappear again.
If you want to remove a particular field from the Profile (e.g. if you added the "Financial Type" field to this profile), click on View or Edit Fields for this Profile in the screenshot above and look for that field to disable or remove it.
