You need this at the top of your config:
[BLOCKCHAIN]
blockchain_source = bitcoin-rpc
Then you need to input your rpc user and pass in the correct spots of the file. Also I see you have "socks5=true", you should comment the line for the clearnet irc channel and uncomment the hidden service.
If you want to spend from your bitcoin core wallet then you need to use "--rpcwallet". Check the "--help" menu.
Here's a sample of my config:
[BLOCKCHAIN]
blockchain_source = bitcoin-rpc
# blockchain_source options: blockr, bitcoin-rpc, json-rpc, regtest
network = mainnet
rpc_host = 127.0.0.1
rpc_port = 8332
rpc_user = redacted
rpc_password = redacted
