Yes....if you are using a channel manager, it is listed under your account. Just to note, Airbnb should not have switched you to simplyfied pricing since your listing is in the United States even with a channel manager. Some Hosts have been experiencing a "bug" with this though. You can find other threads on the CC by typing "split fee" in the "search the community" box.
Host Only Fee
https://www.airbnb.com/help/article/1857#section-heading-1-0
"...With this structure, the entire fee is deducted from the Host payout. It’s typically 14–16%, though Hosts with Super Strict cancellation policies may pay more, and fees for stays of 28 nights or more may be less. This fee is mandatory for traditional hospitality listings–such as hotels, serviced apartments, etc., as well as software-connected hosts(unless most of their listings are in the USA, Canada, the Bahamas, Mexico, Argentina, Taiwan, or Uruguay)."
That said, you can disconnect the channel manager, but other Hosts report they are not able to then choose the split fee option, even when doing this. You will have to contact Airbnb CS about it.
