Get your taxes done using TurboTax

You have to sort this out with the IRS.  And...you say you received that letter "a few months ago".....you cannot ignore a letter from the IRS and not respond to it.   If they are charging you interest --the amount you owe is going up.   TurboTax gets no information from the IRS after you file your tax return.  This is not an issue that TurboTax can help with.   You say you were being paid "under the table"----and now it has come back to bite you.   Sorry.
