I just submitted my taxes, it tells me to mail Form 8453. Attach the following items: Form 8949 or an acceptable | Continuation Sheet for Schedule D. Where do I get it?

I was pretty sure I imported through the connect buttons all the transactions for my 1099-B, is this a bug that I still have to submit this by hand?

I just noticed that on my complete pdf, I have a lot of 8949 form on it, do I need to print those pages? Or do I only need to mail the Form 8453? Thanks

I'm pretty sure that you didn't "import"; is every single trade you made during the year on that Form 8949 that's part of your income tax return?  If not then you didn't import, you told TurboTax that you'd enter "summarized" trade information.

You must report each and every sale to the IRS.  You do this by filing out Form 8949.  That information comes right off your 1099-B and if you enter sales "one at a time" each sale is listed there for you.  But if you "summarize" then you must submit either a Form 8949 or a schedule of some sort with the same information on it to the IRS.  The Form 8453 is the "transmittal" form used to send in the Form 8949 or substitute.  (You probably can send in a copy of your 1099-B if each trade is listed there with the same information that would show up on a Form 8949.)

Thank you for the explanation. Turbotax should add a prompt saying that if you laze out and enter the summarized info, then you will actually have to print several pages later and mail out a form. Had I known this before, I would have spent extra 30 seconds to split the entries as opposed to spending ages on snail mail.

I have suggested that to TurboTax; I'll bet lots of people NEVER mail that information in.
