You may have seen a reference to receiving a foreign gift in TurboTax in order that you be aware of the filing requirements, but there is no place on your Form 1040 to mention that, so you don't need to address the issue when filing your regular tax return.
You can use these links to the instructions for Form 3520 and the Form 3520 itself to prepare the return and file it separate from your federal Form 1040.
