No, you do not need to attach a copy of your 1099-B with your PA return provided the number of transactions does not exceed 10,000, which is the maximum number TurboTax can accomodate. The electronic file will include the transactions showing on your statement provided you entered them correctly. If you are filing on paper rather than electronically you may want to include the summary page of the 1099-B but that is the only situation I can foresee that would have you include the form.
