How do I report a dividend under $10 if bank does not send 1099-DIV

You can enter this into your return without a form. Credit unions and banks sometimes use the term dividends instead of interest, but it would be reported as interest on a 1099-INT if the amount was over $10.

Here is how to enter that in TurboTax:

1. Select Federal on the left side menu.
2. Select Wages and Income toward the upper left.
3. Scroll down, or expand the list and find Interest and Dividends.
4. Expand that section and find Interest on 1099-INT.
5. Click on Start to the right.
6. Answer the first question Yes.
7. Click Continue.
8. Click on Change how I enter my form in the lower right corner.
9. Select Type it in myself.
10. Fill in the first box with  "Your bank name".
11. Put the amount of interest in box 1
12. Click Continue.
13. Select None of these apply, and click Continue.
