Does this help at all for "which Bitcoin" am I using?
Yeah. That's a bitcoin cash wallet.
Did you buy your "bitcoins" (Bitcoin Cash) there aswell?
I'm not sure how easy it is to export/import private keys with mobile wallets. It might be more convenient to use a PC.
EDIT: AFAIK, you can't access your private key on Android Electrum.

Electrum.
NOT ElectronCash, as they might generate seeds differently etc. I have no clue how they work.From there you can export the private key into a BCH compatible wallet (ElectronCash), and you should be able to access your funds.
