Hello JA Customer,
Yes, you will need to file an amended return to report that interest as part of your taxable income. If the amount was only $654, this should not result in a huge tax increase, but it will of course raise your taxes some. The IRS receives copies of those 1099 forms, so if you do not file an amended return on your own, then at some point the IRS will eventually notify you about the discrepancy, and by the time that happens they will have also added interest due for the late payment. So you are better off to go ahead and file an amended return now on your own.
Turbo Tax has an option available for you to fill out an amended return on their website. But unlike your original return, an amended return cannot be e-filed. Once it has been completed you will need to print out the amended returns and mail them to the IRS and to the state along with any additional payment that may be due.
