First, income from a savings account is "interest", even if the institution calls it a "dividend" (as credit unions often do).
The IRS says “Even if you do not receive Form 1099-INT, you must still report all of your interest income.” See IRS Publication 17.
However, your bank or financial institution is not required to send you a 1099-INT if the amount of the interest is less than $10. See IRS Instructions for 1099-INT.
If you have not received a 1099-INT, then get the amount of interest from the end-of-year statement on your interest-bearing account, and enter it into TurboTax.
Go to Federal Texas->Wages & Income->Interest & Dividends and click on “Interest on 1099-INT” (even though you don’t have a 1099-INT).
In the interview, pretend that you have a 1099-INT that you will type in yourself. Enter the name of the institution that paid you interest and the amount of the interest. Do this for both banks, and you’re done.
