Get your taxes done using TurboTax
If you can download your 1099-B as a PDF, you can then Enter a Summary in Lieu of Individual Transactions. The IRS has copies your 1099's if they have issues with any certain transactions.
If you're using TurboTax Online, you can attach a copy of your PDF to your return.
You can add a second business in TurboTax and have two Schedule C's in your return. In the Business section, on the business summary page, choose 'add another business' or 'add another line of work', depending on whether you're using TurboTax Desktop or TurboTax Online.
