Although this topic is old, I thought I'd chime in.
TurboTax does have a feature where the PDF version of a return can be imported into their software. Unfortunately, it is designed to take a prior year's return from TaxCut or Tax Act (primarily) and import it to the current year's TurboTax file. (i.e. Import Last Year's Data) Sadly, it doesn't usually work (poor implementation on TurboTax's part).
Also, there are ways to get from PDF to csv, but in this case, it wouldn't be appropriate.
