Unable to select financial institution from the list

If you are unable to select your financial institution, you can enter your documents manually.

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"
6. Enter FEIN from payer, payer's name, and amount of interest. Choose recipient's name from dropdown box. 

Turns out to be user error. :(
