Verifying Addresses

I am very new, and very interested in the cryptocurrency world. I have an Etherscan account that I would  like to transfer/trade/swap my funds to an external wallet, however,

I don’t know how to verify my addresses, import my API keys, or much more that that. I get very lost and confused trying to work through most instructions I’ve found.

Can you please give my instructions that I can understand and figure out???

I’ve been at a stand still and its bugging me 😉
