IRS-supplied income but no 1099, how to input to TurboTax?

My 2023 tax refund was delayed because the IRS needed more information. I involved the IRSTAS via my Congresswoman and the IRS finally released my refund with about $100 interest on about 2/24/2025. In the close-out letter from TAS, the agent said the interest was reportable - she said "As a reminder, the interest paid with this refund is considered taxable income received in 2024". I did not receive a 1099 for this interest income.

 

Where/how in TurboTax do I add this no-1099-documented income?

 

What is the IRS's TIN or EIN?

 

Anything else particular to this situation that would affect my 2024 filing?
