How do I check where the coins are distributed?
Well if you're referring to your wallet, then by coin distribution I actually mean how your coins in your Electrum wallet are allocated. Some people make use of both lightning network in addition to their normal bitcoin network (on-chain) wallet. So if you receive coins via a lightning channel Electrum recognises it.
Same way it recognises if you receive some coins on chain. If you click on wallet and then coins on you app either mobile or desktop you will get a complete detail of how much coins you have on chain and how much you have on a lightning channel.
