Thanks for the answer David! So, in a paper filing (and presumably in an e-filing) , it sounds like what gets sent to the IRS is what prints under the selection "All official forms required for filing". Is my assumption correct? Those forms show only totals for wages, qualified dividends, capital gain distributions, IRA distributions, and pensions and annuities. Since my return contains multiple entries under each of those categories, I wonder how the IRS is able to match individual W-2's and 1099's to my return. About all their matching system could do would be compare the totals of all such items to the totals in my return, but it would not be able to specifically match individual items. I'm sure that TurboTax does it correctly, but I find it curious in light of the level of detail I'm used to seeing from the tax software I'd used in the past.
