Get your taxes done using TurboTax

I received a letter from the IRS Letter 6470.  I never claimed any dependents and they say I did.  They are saying I made over $75,000 and I don’t come near.  If I don’t answer the letter they will begin collecting taxes due.  There was a problem with RRC payments and I left one accidentally out ( the $600) payment early in the year.  I was awaiting the 1040-x or z form from turbo tax to correct and they sent me a letter they had corrected it.  Now I get this letter threatening collections and US TAX COURT.  I didn’t even make $20,000 as I’m on social security and that’s it.  Also, they said I left out the name if one dependent and I never submitted any names whatsoever.  I file individually and my grown children (40’s) file their taxes independently.  So, I’m clueless what they are doing making up such a scenario.
