Get your taxes done using TurboTax

Hi MaryFrancis and others, I just got my second audit letter, the first was for 2018 and this one for 2019. Same issue a TURBOTAX error from 2009/2010 carryover of AMT tax credit!  Has anyone been successful in using Audit Defense (Turbotax) or 100% Accuracy to get penalty, interest or underpayment waived?
