Thank you colleagues!
This is the first time I have been working with the exchange and with USDT, so I was a little mistaken

I sent USDT to ETH address, but need to USDT address (Why are they so alike?).
I copied this address from here:

And here is my transaction (sorry, I decided to blur some details just in case):

And that in the upper address belongs to the Pit, but where did the lower address come from?
So if it's an address you own on blockchain.com you can get the private key or seed and import it in a wallet to recover the access of your tokens. But if it's only an exchange address you'll have to ask them to send back your tokens, unfortunately they certainly will require fees for doing that
