Is there any reason I did not receive an 1099-Int from my bank?

Yes if it was under $10.  But you still have to enter the amount.
 You must report all your income no matter how small, even $1 of interest that you don't get a 1099 for.  Enter interest received like a 1099-Int under
Federal Taxes tab
Wages & Income
Interest and Dividends
Interest on 1099INT - Click the Start or Update button

Put the interest amount in box 1

Any amount of income that is more than 49 cents is reportable and taxable.

If the amount is less than $10, the bank does not have to send you a 1099-INT, but you are required to report the income. You report it as if the bank had sent you a 1099-INT. Just put the bank name as the payer and put the interest in Box 1.
