Just to make it a little more clear - I have already got pre-approval for mortgage. I do have the money to put in 20% down payment as well without this gift money. I am trying to bring the goft money, so my loan amount will be less and i will not need to pay more mortgage interest & per month

The link from the IRS is correct.  The fact that it is filed in the web site section on businesses is irrelevant, the instructions for the form are clear.

You must report gifts from foreign corporations or businesses of more than $14,000 per year or gifts from foreign persons of more than $100,000.  There is no tax owed when receiving a gift, this is a reporting requirement only.
