Get your taxes done using TurboTax

Thanks John.  Very helpful.  But I have one more important question.  I seem to remember seeing on one of these threads that, after Efiling, within 3 weeks, I would need to follow up the summary with an additional form  which actually details my trades.  Is that correct?  If so, what form, and how long do I have to get it to the IRS?  What happens if it is late.

 

Thanks again : )
