Solution

const a = [
  {
    "0": {
      "itog": 12860498,
      "return": 1107294,
      "beznal": 10598131
    },
    "date": "2021-01-31"
  },
  {
    "0": {
      "itog": 20156554,
      "return": 1147363,
      "beznal": 18127393
    },
    "date": "2021-02-28"
  },
  {
    "0": {
      "itog": 19187309,
      "return": 1667656,
      "beznal": 17597434
    },
    "date": "2021-03-31"
  }
];

const result = a.map(function(i) {
  return i[0].itog;
});

console.log( result );
