Hi TT community. I found an answer to my recently posted question. I will report interest income from IRS under miscellaneous reportable income. NNTR. Thanks

You can report that under Interest Income since it is interest from the IRS.   Enter it like you have a 1099-INT in the interest section of TurboTax.   

Form 1099-INT reports interest from banks, brokerages, and other financial institutions (and the IRS).  Here's how to enter a 1099-INT:

1. Sign into your TurboTax account.
2. Open or continue to your return if it's not already open.
3. Inside TurboTax, search for 1099-INT and select the Jump to link in the search results.
4. Answer Yes to Did you receive any interest income?
   • If you see Here's the interest we have so far, select Add interest income.
5. On the following screen, select how you want to enter your 1099-INT (import or type it in yourself) and follow the on-screen instructions.   You only need to enter IRS - US Treasury and the amount.
