* Do I need just to print Form 8453 and 8949 from TurboTax prepared return and mail it to IRS?
* Do I also need to attach 1099-B showing details of the transactions?
If the Form 8949 that TurboTax prepared is just summary entries, you have to send a copy of the 1099-B showing all the details. You do not have to send another copy of the 8949 that was included in your tax return. The 1099-B is the "statement with the same information." Send a photocopy, not the original.

* I could not send these docs within 3 days of timeline as told on multiple discussions. Can I send it outside the window? Do I need to complete any other step since I missed the 3 days window?
Yes, send it now, as soon as you can. You do not have to do anything different because of missing the 3-day window.

Would my return be incomplete unless IRS receives my documents?
