unrecognized output wallet when using Electrum to send bitcoin help me understand this transaction - https://www.blockchain.com/ro/btc/tx/1318a3e54cff78fdd8f6b54e6fe5115072586091788c9bfa08ca82d83e4bc276 .
Never sent bitcoin from hardware / hot wallet before so I am new to this
So I tried a demo send from one wallet ****c276 to my crypto.com wallet **xmhue

so I understand that my wallet was converted to a new wallet ****qhev with the remaining amount

what I don't understand:

0.001 of my bitcoin got sent to the correct crypto.com wallet, but 0.001 of my bitcoin got sent to a unrecognized wallet - ***myAn - I don't understand what this is
I don't know how Electrum chose that wallet for sending the payment , is the choosing of the wallet automatic from Electrum ?

Maybe its a change address. You can read about change addresses in the below links:
What does change address mean inside Electrum wallet?
What all the addresses are in my Electrum wallet?

I am not sure why change address is starting with &quot;3&quot; which can be a p2sh-segwit address because input address bc1qxesjp5g4d23kpt9xghwxlu4mfhu9xxrehp0ytnm023ely43kdh9spsy4k7 is most likely an address from 2 of 3 multisig wallet with p2wsh addresses.
