Whether or not you have to mail in the forms depends.
If all of your transactions are "covered" and there are no adjustments, then you can enter summaries only and not have to mail in any forms.
It is unlikely that any software is ever going to import 3000 transactions in a way that makes your life easy - with that many transactions there are going to be too many issues that will require adjustments, etc. At least not until everyone has sold all positions that fall outside of those the IRS considers "covered".
The BEST way to handle these is to use the summary options and skip import if you have a lot of transactions.
It isn't contradictory to the IRS instructions, it's exactly what they prefer.
Use the summaries and mail your transactions in (or use a professional who can do it for you - or a software program that allows you to attach the PDF.) Creating the option to attach the PDF is something perhaps TT should do - but finding a way to import your 3000+ transactions is not. If you had 2999 and could see what a mess that makes for you in ANY software, you wouldn't be asking for that anyway. I promise.
