I received the same prompt about W-2c. Note: Max Wages subject to Social Security Tax Withheld for 2020 was $137,700 with Tax Rate = 6.2%. Quick Calc of Max Tax Withheld = $8,537.40. My W-2 form block 4 reads $8,537.40. Therefore, there is a bug in the TurboTax Premier Software. Recommendation: "Fix The Glitch."
