Yet another rookie mistake?!

Hi guys! Sorry for this post, I guess I am not the first one doing this but I would really appreciate your support!

I am entirely new to Metamask, I set it up a couple of hours ago. I started to transfer USDT from Binance using this guide:
[Not allowed to share links yet, but the youtube video is callet HOW TO: Deposit BNB/BUSD/USDT From Binance to MetaMask Wallet (Transferring 45,000$ USDT))

In that guide he uses BSC/BEP20, which I did also. But the USDTs did not arrive to Metamask wallet, obviously. Is this the correct Network to use?

I read another post how to add the token via contract ID (0x55d398326f99059ff775485246999027b3197955), but that does not work either.

I cant upload pictures now, as a new user. But the transaction looks successful. Transaction hash:0x3b37628042b4dd13871b98104547574272c14ba7fd6f482f4a8aa5af35245395

What can I do to retrieve this, if it is possible?

Just needed to add BSC Network!

I will find my way out
