Before doing the interview i was charged by the default fee but i got charged again after i completed it
Viewing post in About the tax interview fees
As I’ve said three times now, you will need to create a payout request to see a full breakdown of revenue, including any fees. Fees do not double out of nowhere, and the way we handle revenue is very specific and well documented, so it’s likely you have a misunderstanding about how it works. I recommend reviewing our guide on getting paid: https://itch.io/docs/creators/payments
I am unable to offer you anymore information at this point unless you have a Payout ID you want me to look at.
Thanks
