I do not think that this one is the one known as Binance-Peg BTCB Token (BTCB) since the Binance-Peg BTCB Token (BTCB) token contract is 0x7130d2A12B9BCbFAe4f2634d864A1Ee1Ce3Ead9c  while the BTC sent to your BEP20 address is 0x63af599cd4837e56526f3C2C57dF5251a80715b2  which has 50,000,000,000 supply

So I guess you received spam token more or less.

If you wanted to access the sent BEP=20 BTC, and has the address on your metamask, you can add the token by simply following the this instruction: https://www.coingecko.com/learn/how-to-add-binance-smart-chain-bsc-to-metamask, if that is a spam token used to hijack bep20 address, be mindful that accessing its website may incur losses of your fund.
