Thanks for the step-by-step.

I need to study it for a few days make sure I don’t mess up.

Try those steps with a small amount first. If you decide to install mycellium app (which I can't vouch for but use nonetheless), then you can verify that small amount really went from coinbase's stash (which they own but pretend some of which is yours) and got transacted to your brand new address.

Furthermore you will know that the private key was readable by the mycellium app and you can spend at some point in the future.

There's a detail I left out in using the mycellium app. You have to click on add key icon like usual. But then you must scroll down to advanced and use "Scan". The warning right above that say that there is no backup. But that piece of paper in front of you, about to be put in your safe, is your backup. So if it all works, then you know your backup works.

But be sure to use "Advanced and more" and click scan to copy the private key from the paper into your mycellium app. Do not "sweep". Some apps only "sweep". If you sweep then the proceeds are transacted from that private key to a new private key and the paper backup now has a balance of zero.

Yeah...study always helps before “jumping in”, basically like FReeper Palmer said above, you can derive your private key from CoinBase, but you DON’T want to use that CoinBase private key to transfer the funds to an “intermediary” wallet before you record your seed words in steel. CoinBase could use that key to drain your Bitcoin later if they wanted to...you need a new private key and TRANSFER/SEND your Bitcoin to the new fresh/unadulterated by an exchange BTC wallet address/private key. So: from exchange/CoinBase-—>send BTC-—>to new never used BTC wallet/private key-—>record seed words from the new trusted/fresh wallet-—>stamp seed words/phrase into steel-—>delete “intermediary wallet”-—>put seed words/phrase in a safe place.
