'A' has one bitcoin. 'A' tries to send a 0.5 bit coin to 'B'.
Two utxo are created.
First, "utxo" sends "B" 0.5 bitcoin. Second, "utxo" where "A" remits remaining bitcoins to "A" except for 0.5 bitcoins and fees.
utxo 1) A-->B
utxo 2) A-->A
The url below is the URL to see how UTXO is reflected in the Bitcoin block detector. https://www.blockchain.com/ko/btc/address/1JK1MAseF6TRjBidxz45T1VnYVFummCTBZ?offset=5250&filter=6

Sometimes when you look at a block detector, there's some TX information that you don't understand.
For the following URL, the coin in the wallet is used to transfer the same bitcoin from several wallets to another.
There is also a "TX" that displays only the amount of coins received from one wallet.
In the case of the url below, I transfer Coin from my wallet "13E3dBUWUHV8XpgJib795yqRTmyX47jWMk" and there is no utxo sent to my wallet.
utxo 1) A---->B
utxo 2) A---->C
If this is how the money is transferred, can we know why this is happening?
