After repeated calls over a two year period to the IRS about a 2021 tax refund, they are now requesting a letter from my company stating date of employment, gross wages and withholding, for the year 2021. The W2 was initially provided but they want this letter too. They said give them an additional 120 days to process.
Is this normal practice? The return was prepared via TurboTax and the IRS never requested additional information until today. Should interest also be included for this two year period?
