If the dates of stock acquisition on the 1099-B are incorrect and I imported the 1099-B, how do I correct those dates in TurboTax?

The dates shown are the dates the certificates were transferred to the broker for keeping (so the 1099-B incorrectly shows the sales as short term gains), but the original acquisition date is much earlier (long term gains.)  Can I just correct the 1099-B numbers in TurboTax and/or do I have to get the broker to issue a corrected 1099-B?
    Yes, you can make the changes within TurboTax, if you know the dates on the 1099-B are incorrect. I would highly recommend following up with your broker to ensure their data is updated accordingly as well from a historical and documentation persepctive.

      People come to TurboTax AnswerXchange for help and answers—we want to let them know that we're here to listen and share our knowledge. We do that with the style and format of our responses. Here are five guidelines:

      1. Keep it conversational. When answering questions, write like you speak. Imagine you're explaining something to a trusted friend, using simple, everyday language. Avoid jargon and technical terms when possible. When no other word will do, explain technical terms in plain English.
      2. Be clear and state the answer right up front. Ask yourself what specific information the person really needs and then provide it. Stick to the topic and avoid unnecessary details. Break information down into a numbered or bulleted list and highlight the most important details in bold.
      3. Be concise. Aim for no more than two short sentences in a paragraph, and try to keep paragraphs to two lines. A wall of text can look intimidating and many won't read it, so break it up. It's okay to link to other resources for more details, but avoid giving answers that contain little more than a link.
      4. Be a good listener. When people post very general questions, take a second to try to understand what they're really looking for. Then, provide a response that guides them to the best possible outcome.
      5. Be encouraging and positive. Look for ways to eliminate uncertainty by anticipating people's concerns. Make it apparent that we really like helping them achieve positive outcomes.
