how do we both itemize on married filing separate?

It says we both have to itemize, but it seems if we both try to claim the mortgage interest and our child that is do we split it?
    You can split the itemized deductions any way you want, so you should put most of them with the higher income spouse.

    Personal items, like the W-2 state & local withholding on an individual's W-2 can only go on that spouse's return.
      If she itemizes, you must itemize, but only one of you can claim any single deduction.  This is one of the reasons why married filing separately typically results in a higher tax obligation than if you file jointly.
      • We have had to file married filing seperate for several years because the state of ohio is very unkind to married people.  How do you do it in Turbo Tax I have not used it before.  I entered infromation under joint but I need to change it because once again it will cost us more overall to be married.
      I don't know Ohio but I find that hard to believe.  You probably can file a joint federal return and separate state returns.  If you're filing separately then don't enter both into one return.

      The online version is only good for 1 return. To do another you have to start over with a new account and user name and pay any fees again.  And the state return is extra to prepare, whether you efile or print to mail.  That's why if you have more than 1 to do it's better to buy the desktop version.  And in the online version you can not see or enter into the actual forms.

      With the Desktop version you can prepare and print unlimited federal and unlimited state  returns and efile up to 5 federal for free (IRS limit). And it has what if scenarios and you can see and enter directly into the actual forms.  State is $19.95 each to efile but it is free to print and mail unlimited returns.  If you buy the cd at the store the Basic version does not include the state.  And Deluxe is available both with and without the state.  Because some states don't have an income tax.  Look around for sales at stores.  Or you can buy a cd or download the program hereā€¦..
        Here's the problem in Ohio: Unlike the federal tax system, Ohio does not have separate tax rates based on your filing status. The 2nd spouse's income is added to the first spouse's income and that total income is pushed into a higher tax bracket. So, a single person and a married couple making the same income are each taxed at the same marginal rate. Ohio tries to compensate for this with a Joint Filing Credit, but it is limited and doesn't always make up for the higher rates. Ohio requires you to use the same filing status that you used on you federal return; so filing a joint federal return and separate Ohio returns is not an option.

          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.
