If you RECEIVED the gift, there is no tax consequence for you.
YOU do not report gifts as income. The tax was already paid by the person that gave you the gift.
If the gift is over the yearly limit, the person that GAVE you the gift needs to report that by filing Form 709.
Form 709 just keeps track of how much money a taxpayer gives away during their lifetime.
The limit is quite large.
For Tax Year 2023 it is 12.92 Million USD
