Why won't the mortgage interest numbers I put in show up on Schedule A? They total more than $24,400

Go back through your mortgage interest section and double-check that you have indicated that the mortgage is secured by your residence.  This is something that is easily missed and will automatically make your mortgage interest not deductible.  

Use these steps to return to the mortgage interest section of your return:

• On the top row of the TurboTax online screen, click on Search (or for CD/downloaded TurboTax locate the search box in the upper right corner)
• This opens a box where you can type in “mortgage interest” (be sure to enter exactly as shown here) and click the magnifying glass (or for CD/downloaded TurboTax, click Find)
• The search results will give you an option to “Jump to mortgage interest”
• Click on the blue “Jump to mortgage interest” link
