How do I change my 2-Step Verification?

In the past, when I logged into Gmail, the 2-Step Verification page came up & I used the Google Authenticator App (on my phone) to get my code & then I was let into my account.
But for the last few weeks, when I log into Gmail, a code is automatically sent to my phone & I do not want it set-up this way.
I find no email to contact Google to get help in changing this setting. Does anyone know how I can change this setting back to the way it was before?

I don't want to TURN OFF 2-step Verification, I want to change it back to the way it used to work.

Try: Google>Manage account>Security>2SV: click on RH arrow, it will ask you to confirm password, which should then show the available second steps, and which you are using. As I am using them all, I don't see an option to add! I don't think I can link to anywhere helpful, as it will be to my account.

I opened Google>my account>Security>2-SV & below is what I see. There seems to be no way to change this setting.
I guess I'll start using the Google Prompts to get used to it. Hopefully it's just as secure.
There should be a distinction, as I'm using my desktop computer, not phone.

do you not see below 'backup codes' an option to add more second steps:

Yes, I do see "Add more second steps to verify it's you", but I don't want to ADD another step, I want to RETURN to the way it was setup before, (using the Authenticator app).
I'm just going to start using the Google Prompt & hopefully it's just as secure.

Can you not follow their suggestion to 'sign out of that phone' (that gets the prompts), and then add (or re-instate) the app on the phone?

I'm not using the phone, I'm going into Gmail on my desktop computer.
