I filed my taxes using turbotax desktop software. But turbo tax online says i did not file my taxes using turbo tax. I am looking for my AIG, how do i go about it?

If you used the desktop CD/Download editions installed on your computer, the only copy of your tax data file and any PDF's will be on the computer where the return was created.  TurboTax does not store online any returns completed using the desktop editions.
