"Heads up! You have a W-2c coming. You deferred some Social Security taxes." I only have imputed income from life insurance. My W2 shows correct amount of SS tax owed.

On my W2, Box 12 code M (uncollected Social Security tax on group term life insurance over $50,000) shows exactly 6.2% of box 3 (Social Security wages from imputed life insurance income). There are no deferred Social Security taxes. There is no W-2c coming.  I am filing online with Turbo Tax. Is this a online Turbo Tax bug/error? Can I safely ignore this incorrect notice?  Is there anything I am missing?

Yes, ignore the notice.  It was also in the 2020 program and should have been removed for tax year 2021 but was not.
