I uploaded an AI-generated asset but forgot to select the "Created with AI" option. It was approved

I can look at most images and tell if they are Generative AI or not.  I think most people can. 

That said, honesty is the best policy.  You don't want to be penalized for making a mistake of omission.

Are you sure Adobe did not automatically change it to be categorized as an AI asset? If it is not marked as AI, you should delete and resubmit correctly. Selling an AI asset without accurately portraying it as such is misleading to Buyers and can put your account in jeopardy.

BTW: Contributor related questions should be asked in the stock contributors' forum.

I uploaded an AI-generated asset but forgot to select the "Created with AI" option. It was approved and has now reached 100 sales. What shoul

That is bad, as things like that can get you blocked if you do that regularly. For a one-time offence, proceed as @yamato713108855 told you. Nb: maybe you should check your other assets too.

You should delete it and register it again.
If you sell it with the wrong settings, it may be deleted later.
