I finished my tax return and e-file them already, how do I know which document I still need to send into IRS?

Turbo tax used to put all of the documents that I need to send in either in the beginning or the end of the document, but now it's like a treasure hunt. Do anyone know how do I know what I need to send it?

If you e-filed you do not mail anything.  It is all done electronically.  Save a copy of your tax return and save your W-2's, 1099's etc. for your own records.

If you e-filed, there are only a few documents you might need to mail in, but this is uncommon.  View or print the PDF of your tax return and pay close attention to the instruction page.  If you do need to mail something, you will also need to print a form 8453 which is a cover page, and that will also be in your PDF package.
