How to Mail - trade details

In the past my CPA used to enter only totals from sales of stocks (both long and short term) and then e-file Tax return but mail the sale details from my 1099 to IRS. Tax prepares can not import 1099 into their software so they have manually enter every thing.

According to him, it was to save me money and I was paying him for time or how many forms or lines he has to punch.

How can it be done within TT and is there form to be mailed along with securities sale detail? What is form number or how do get mailing instructions with TT?

Can it only be done for sales of securities or any other form which can not be e-filed mailed to IRS but tax return itself filed as e-file?
