The only PDF you can attach -- sometimes -- is a detail record of stock transactions in lieu of Form 8949.
No, not anytime. Although that may be the case with respect to personal versions of TurboTax, users are not prompted for this kind of attachment nor do the mailing instructions appear in TurboTax Business as they do in the personal versions.
Users can attach files with any combination of forms when they are prompted to attach a Form 8453, but whether the IRS will process those forms is doubtful (and it probably goes no further than the TurboTax servers).
