Hi - I received a letter from the IRS stating that my "Forms W-2 are insufficient to support the amount you claimed for excess social security and tier 1 RRTA tax withheld on your Form 1040". The problem is, I have no idea how this value was entered into Turbo Tax or where it came from? I have no memory or record of doing so. Is this auto-calculated, or is it a field entered through the guided forms during tax preparation? I'd like to understand the source of the number so I can determine my best course of action. Any help is appreciated!
