Edit: I just read the following on another site, which leads me to believe that it was sent back to the broker. I appealed my case with them once again, and this time was able to convince the chat guy to forward it to their technical team. Fingers crossed!
"An unspent transaction is the amount of cryptocurrency not spent during a transaction. This unspent amount represents the output of a transaction that is sent back to the user. The unspent output can then be used for future spending."
Don't mind that Quora article since part of it is misleading.
Every
UTXO in your wallet are unspent outputs from inbound transactions that you've received or "
change" of your outbound transactions.
The user is most likely talking about the 'change' in that post and regarded that as UTXO in general.
Regarding the change, it's the excess amount from the input used by the sender's wallet;
It's not something that reverts the transaction back to the sender.
for example: in the latest transaction in the OP, your address received the intended amount and
3EGRD6N...249EwaQSVJ received 0.44538365 BTC change from the 0.44790063 BTC input.
If the transaction
8efc0a4a01f0ab0ed57e5dcfc19d548d94ffaa4f436b8a631f33e940fb775e0c has the correct address, it's CashApp that you need to contact.
