So I’ve created a Paper wallet using bit address.org, and have joined Blockchain.com, but can’t find out how to link the two?

Also the strategy I’m using at the moment-till maybe “you” say otherwise, is-I’ve bought Bitcoin using Coinbase, and am trying to send money to my bitaddress.org Paper Wallet-but Coinbase isn’t showing me how to do this? So I can then register the transaction-and others on the Blockchain on blockchain.com Do you think I’m using the right strategy?
