My federal return was rejected when I filed electronically and TurboTax is telling me this is the problem:
"If Form 2210, Part II, Line A checkbox 'WaiverOfEntirePenalty' is checked, the [waiverexplanationstatement] must be attached to Form 2210"
This sounds like a TurboTax issue (i.e. not a
data entry issue on my part) since Box A in Part II of Form 2210 is checked and
TurboTax entered "85% Waiver" next to it? Not sure how to proceed, so appreciate any insights anyone can provide!
