3. If you haven't entered any interest income yet you will see the screen, Did you receive any interest income?  Click the Yes box.
4. On the Choose your bank or brokerage screen, click on the I'll type it in myself box.
5. If you've already entered interest, you will see Here's the interest we have so far. Click Edit next to your entry for the bonds. [or Add interest income if the interest in the table is not the bond interest.]
6. On the next screen, Let's get your 1099-INT or brokerage statement details, click the box My form has info in more than just box 1 (this is uncommon).
