I received a letter from IRS indicating I owe money (including penalties and late fees) for a mistake I made on my 2015 return. I inadvertently lost the letter; therefore, I need to get a copy to research the issue. I want to know if there is a section on either the IRS website or in backup documentation under my Turbo Tax account where I can print out a copy of this notice. Also, is there a way I can find out if I will receive any additional notices from IRS for mistakes I made in other year returns. Thanks
