In my 1Password Windows app, the Import option is disabled.

Hello @cactusyoyo,

Thanks so much for your messages and letting us know that you have been able to solve your troubles after confirming the account for your wife.

We've seen some cases with customers not being able to move (import) data from LastPass to 1Password due to the option being greyed out in the app's menu. I've merged your thread here as these details may be useful for other customers who are still seeing troubles.

If this is the case for other customers, please be sure to follow the steps here to Add a family member where it notes:

Each family member you invite will receive their own Secret Key and create their own account password to use on their devices. After each account is set up, you’ll receive an email notification. Click the link in the email to confirm each account.

Do let us know if any others are continuing to have troubles.
