You can fix this in several ways, I recommend you download Electrum.
In Electron Cash, export the private key for 1KmQfQKXemUtDkJt9hN6w8Si984CM7JUTb. DO NOT show the private key to anybody!
Install Electrum, create a new wallet > Standard wallet > Use public or private keys > enter your private key into Electrum.
After this, your 0.044 BTC should show up in your Electrum wallet again.
Note that you got lucky: if you mess up Bitcoin and Bitcoin Cash when depositing to an exchange, it's very likely you'll lose your money. Be careful not to mix up different chains again!
