Account Locked

Second insta account is locked. Trying to change password but I have 2fa on and no access to backup codes and authenticator app was deleted (nothing was stored apparently) 🤦🏻‍♂️ (I know, I know). Keep getting stuck in a loop. Tried "I've been hacked" route and whatnot. No pics of me on grid of that account so selfie upload gets no result. Main account has been verified for about 9 years - Can that help me? At this point, I just want to get in to and delete second account.
