Can I suggest you to use Ledger live?
Here see the instructions:

Keep it simple and just follow the step by step information they have provided in their website. You can do it using Electrum later. Your coins are really safe, please do not stress out.
I was going to suggest exactly that.
Electrum is amazing for more advanced users. Newbies can stick with ledger live, and when he finds his coins he may try Electrum again.
