Verifying foreign phone number

I am a US citizen living abroad. I had done my taxes 2 years ago with turbotax and was able to e-file it .. Now I logged back in to do my 2021 taxes... 

 

2 years ago I had entered my foreign phone number to your system which is still the same... (not on to my taxes because IRS doesn't accept foreign phone numbers - which is not fair, considering US citizens in foreign countries are also responsible for taxes)

 

Now after logging into my dashboard, under sign in and security screen I saw a "verify phone number" option which has my foreign phone correctly shown (with the +country code and then phone number format). So I went ahead to verify it. I tried both text message and phone call. But I received none. I do not remember verifying a phone number 2 years ago but I was still able to file taxes with your system. Now what? Will I not be able to do and file my taxes? I have a US phone too but that is only a voice mail.

 

I didn't even start to do my taxes yet I was going through the dashboard after logging in.

 

And also I didn't see anywhere where to start doing our taxes. Do I need to purchase the product first and then start to do taxes? (assuming I will be able to file with you per my question above)
