I sold my primary home during 2016. As it was located abroad I was not given any 1099 form for this. I am not obliged to pay taxes since I lived two of the last five years there. Turbotax offers two options: a) To include this operation in my tax return as "additional information" or b) To exclude any reference of this in my tax return. My question is: What of this options increases more the probability that the IRS picks my tax return for audit? My bank accounts shows clearly the proceeds of this sale.
