I tried searching out and this wallet address is no where showing in my wallet but I clicked on COPY Wallet Address to receive the payment.
How can a wallet address be copied and receive money but doesn't show in my wallet?
As the others have suggested, it might be that you have the clipboard virus that modifies addresses when copy/pasting bitcoin addresses...
As a test, select and copy this address: 1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2 (it's the example address from the Bitcoin Wiki

)
Then try to paste that back into a reply here. Does it come up as 1BvBMSEYstWetqTFn5Au4m4GFg7xJaNVN2 or is it changing to another address when you paste? If it comes in as a different address, then you have the clipboard virus and should take appropriate measures (scan/clean... maybe reformat computer). It's quite possible that as you did this from b.info browser wallet, that it could be a rouge browser extension/plugin.
I dont assume that he have a virus on his pc since when i do saw the address on where those funds have been sent.Theres only one transaction on which those 440k sats have been sent.Its quiet odd that he didnt able to see the balance since its already confirmed.I would like to ask on op if hes sure on having the access on the said address? If yes, can you post a screenshot on where you do request for payment and that address came out? If its the same address then ts worth to send support ticket then if its not then you have a virus on your pc.
