You're less likely to get help in an old thread with multiple users on a hodgepodge of different issues, especially when your issue is quite state-specific. Normally it's best to start one's own new thread with Iowa in the title, and then it might catch the eye of someone in the community forum familiar with Iowa.
Or you can phone TurboTax Support for assistance. You can use this contact form to get a number:
https://support.turbotax.intuit.com/contact
Support hours are 5AM-5PM Pacific (8AM-8PM Eastern), Mon-Fri
Or since you got a state letter, you can contact TurboTax IRS free Audit Support Center. To get the phone number, go to the page below and click the blue "Get Help..." button. It says "IRS letter", but they help with state letters, too. If it was due to a software error, you can discuss it with them or ask to be transferred to another department to someone familiar with the Iowa state program.
