I received a 1099-INT from the IRS but it has a PAYER's Federal Identification Number that I am not familiar with. I looked up the number and it's an LLC that I have not done business with. The amount of interest income is in the $30 range which isn't a concern. I'm more worried about fraud that I may not be aware of. Has anyone seen this and if so and suggestion on how to sort this out? Many thanks.
