Did not receive 1099-INT, but need to report small amount of interest income. How do I do this? Am circling back to having to type in info from a 1099-INT...

All you need to enter is the name of who is paying you like the bank or broker and put the amount in box 1.

 

Enter the interest as if you do have a 1099-INT form, except type it in manually.  See example image below.

 

Enter/Edit/Delete 1099-INT (Interest Income):
1. Open your return (if not already open)
2. Enter "1099int" in the Search box.
3. Click on "jump to 1099int" link.  
4. Enter your information. Continue.
