Hello, I'm not sure whether or not I need to file my 1099-INT form. At the bottom, it says "FATCA Filing Requirement: NO." Also, why is it making me purchase Deluxe?

Yes, you should include your Form 1099-INT as part of your tax return.

The designation FATCA filing requirement NO, refers to the Foreign Account Tax Compliance Act, not whether you should include it on your tax return.

If TurboTax is asking you to upgrade to Deluxe, it means that you are entering a tax item that cannot be reported by using a lower version of the program.
