After you file

I entered my informatiin from my 1099 form but when my return was transmitted to the IRS that information was not. I reviewed everything 3 times before actually filing, and all 3 times it showed the info I keyed in from my 1099. Yet I recieve a letter from the IRS stating my return was missing info. Upon review all that was transmitted to the irs was my w-2 info but no 1099. So my return wasn't accepted.
