All interest is reportable by you, even if it's only $1 or less. It is the bank that is not required to furnish you a 1099-INT if it's less than $10, but the filer still has to report it.
According to the Form 1040 instructions, you would need a Schedule B for reporting it only if the total amount of taxable interest or ordinary dividends is over $1,500 or if any of the other conditions listed at the beginning of the Schedule B instructions applies to you.

If the total amount is such that you don't need Schedule B, then when you enter it into TurboTax, the interest or dividends will appear directly on the Form 1040 and any preliminary Schedule B or Sch B worksheet (if applicable) would not be included in the filing.
