Hi, welcome! 
It seems like you have deployed contracts successfully, and now you are trying to verifying the contract, but sorry, I am not familiar with the BSC-Chain, maybe you should ask for help in their forum: Home | Binance Chain Forum
And they have a documentation about how to verify contracts, maybe you can have a look at it:
If you deployed your contract with the Remix, I think you can have a look at this tutorial: Verify erc20 token on etherscan that was deployed through remix:step by step guide
