cant post interest income on my form?

Yes, you can report interest income on your tax return.

If you are trying to import, try to enter the amount manually instead. Here's how to enter a 1099-INT into TurboTax Online manually:

 1. Open TurboTax Online and navigate to Wages & Income > Investments and Savings (1099-B, 1099-INT, 1099-DIV, 1099-K, Crypto) > Add/Edit
 2. Choose the button Add Investments
 3. Under "Let's import", choose "Enter a different way."
 4. Choose Interest, continue
 5. Choose "Type it in myself"
Enter FEIN from payer, payer's name, and amount of interest. Choose recipient's name from dropdown box.
