If I do my personal taxes (1040) using TurboTax, how do I import a Sched C for a side business that was completed by another firm (PDF format) into TurboTax?

I am employed full-time, but also have a side business that is an LLC, sole proprietor pass-thru.  The Schedule C as well as some depreciation forms has already been completed in PDF format by a separate accounting firm through LegalZoom.  Can I import these documents as attachments to my TurboTax filing, or do I need to re-enter all of the relevant information using TurboTax Home & Business?
