Contact Apple Support:

Ask for assistance with logging in to your Apple Account. Explain that assistance with adding your current iPhone as a trusted device. And be sure to sign in while on the phone. Elsewise, you’d have to call back.

Important:

Calls are taking quite a moment due to the Coronavirus Pandemic. Lots are at home at the moment, allowing them time to contact Apple Support. So, just stay in the phone; you’ll get through.
