The IRS has to actually pull your tax file from the TurboTax servers....and so far, they have only been pulling a few test files. They have said they will not be processing in earnest until ~28 Jan, but could always start sooner...or delay longer.
Until they actually take your file, then the IRS site won't show anything because their computers don't know it even exists yet....it is sitting "locked" on the TurboTax servers.
