For the interest, say you did not get a 1099-INT.
- In the upper right hand corner search box, Type 1099-INT; Click the Jump to 1099-INT link that appears in your search results.
- Click Yes when asked if you received any interest income.
- Choose your bank or brokerage from the list to import your 1099-INT and click/tap Continue or manually enter your 1099-INT by clicking I'll type it in myself and click Continue
