Hi, welcome! 
I really recommend you to use tool to deploy contracts and verify, such as Truffle or Hardhat, it is much easier!
If you deployed your contract with Remix, maybe you can have a look at this tutorial: Verify erc20 token on etherscan that was deployed through remix:step by step guide
And for the next time, please search at the forum at first, and then ask questions, thanks!

I prefer to close this topic, if you still can not verify your contracts following all the tutorials I shared above, you can reply under this topic and ping me.
