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:
I think you can have a look at this tutorial: Verify erc20 token on etherscan that was deployed through remix:step by step guide
And for next time, please search at first and then ask questions, thanks!
