I received a Notice CP2057 from the IRS. It is stating that what I reported for income does not match their records.

The notice states that they have two sources of Misc Income and in the TurboTax return, I have these two amounts listed. I am not sure why they say it is different? Does TurboTax actually transmit the account information for each 1099-MISC or does it just transmit a total amount? I have a third 1099-MISC that is not on the IRS notice, but listed in TurboTax. All three of these amounts is more than what is on the notice. I don't feel like I need to amend the return, but need to find out what TurboTax is sending on my behalf.
