    Declare the variable before the loop, not for every item:

    const mappingFunction = (values: any) => {
  const selectedReasons: any = [];
  values.forEach((reason: any) => {
    if (reason?.isChecked === "false") {
      selectedReasons?.push(reason);
    }
  });
  setSelectedReasons(values);
};

    You define selectedReasons inside your loop which will create a new instance on every iteration. You also pass setSelectedReasons to the values that the function takes in.

    You could use the filter method to get only the values where the reason is false.

    const mappingFunction = (values: any) => {
  const filteredValues = values.filter(
    (reason: any) => reason?.isChecked === "false"
  );
  setSelectedReasons(filteredValues);
};
