This is a very good example of vulnerability introduced by badly organized security system. One does not keep backup access codes in places which are unavailable in case of a failure of primary access methods. Store your 2FAs in a separate phone kept in a SAFE, a combination to which you do remember. Also, adding 2FA to a password manager is probably excessive, just use a really long password which is easy to remember. Like "HowOn5EarthsCanAPersonForgetHisPazzw0rdToPasswordManager?", that'll be enough.
