Turbotax: "You have a W-2c coming. Since you deferred some of your Social Security taxes last year,..." Both my W-2's have maxed-out SS income/withholding, a problem?

I don't recall any deferrals or communications from employers. Both W-2's for myself and spouse have maxed-out SS income and withholding at the 2020 cap. I did enter a small amount as "non-employee compensation" from a 1099-NEC. Could this be triggering Turbotax's message?
