<prompt> Human: I filed my taxes on Turbo tax just as I have done over the last 7-8 years. Just got a letter from the IRS indicating my reported income on my tax from was 10,000 less than reported on my W-2s. I now owe roughly about 3000 including 88 of interest. I contacted Turbo Tax due to their 100 Accuracy guarantee to investigate. They are investigating but their guarantee will only pay the 88 interest if they are at fault. Lessen learned. I will not use Turbo tax again.  <response>: Uhm, what? Thats exactly what the guarantee is for. You always owe whatever tax is due. You just got a 0 interest 8 month loan on the money, which turbotax is covering.
