You can't receive payouts from itch.io into a bank account, it has to be a PayPal or Stripe. And please double-check section #2 of our terms:
If you register an account to sell, distribute, or publish games or other content on itch.io, you agree to be bound to the terms of this Agreement as a platform publisher (“Publisher”). Publishers affirm that they are either more than 18 years of age, or possess legal parental or guardian consent, and are fully able and competent to enter into the terms, conditions, obligations, affirmations, representations and warranties set forth in this Agreement.
Hope this helps.
