401K Rollover/Conversion 1099-R; only after-tax dollars put into ROTH-IRA. How do I show this in TurboTax?

Subject:  I don't want to be taxed on after-tax money from my 401K that was moved (rolled over??)  into a Roth-IRA in 2010 (tax form 1099-R.)

I've rolled-over/converted?? a 401K from old job into 2-ira's.  One is a traditional.  The second is a Roth-IRA that was created from the after-tax money that was in the 401K.

I am filling out the portion of TurboTax relating to 1099-R and I am on the "Any Rollovers or Conversions"  screen which tells me to choose the distribution method.  It is unclear which item I should check.  None of them seem to apply?  The closest answer is "converted the entire distribution to a Roth IRA", but it is unclear to me how this is reporting post-tax dollars.  A conversion, to me, implies a taxable event.  It seems to me this is a rollover, but non of the items provides for a 401K rollover to a ROTH-IRA??

Bottom line:  How do I report these after tax dollars (in TurboTax) such that I will not be double taxed on this amount.  put into a ROTH-IRA

Thanks for your insights....Best regards.
    You will need to complete 2 1099Rs to accomplish this.

    On the first one, enter in box 1 and box 2a the taxable amount rolled over into the traditional IRA. On the "Any Rollovers or Conversions?" screen, select that you rolled over the entire distribution to a traditional IRA or qualified retirement plan.

    On the second, enter the amount rolled over to a Roth IRA in box 1 and box 5, and zero in box 2a. On the "Any Rollovers or Conversions?" screen, select that you converted over the entire distribution to a Roth IRA.

      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.
