What to do if I got a letter 4464c

IRS Letter 4464C means that your return was selected for additional verification, which could take approximately 60 days. You don't need to take any action unless told by the IRS. This verification includes reviewing your income and/or withholdings. This doesn't mean that you did anything wrong as this could be a random verification.
