I’ll forward this to my friends at Google if you promise that you stop using Google products.
Anything! Please let them know my recovery account (another gmail, FirstnameLastname) is also locked. Edit: I'm back in to my recovery account!! Just enabled 2FA to avoid getting locked out again. My main account is still locked, but it let me verify via my old password, new password, and recovery email code. The message says that they still need to verify more, but I should look for an email to login within 48 hours…
Obviously I'm re-working my email solution as we speak... starting with backing up my Google data!
Lots of good recommendations in this thread. Learn from my mistakes. It can happen to you!!
