Why does it say Line 22. Column (c) cannot be later than the date vested when it is not?

When I run the Review, TurboxTax Premier gave the following error:

Form 1099-N Workseet (MyBroker) -- Capital Asset Sales Wksht (1) -- Capital gn (ls) adjustment/other info (XXXsh MyStock) -- Employer Stock Worksheet: Line 22. Column (c) can not be later than the date vested.

But it is not:

The date vested is 5/15/2021

And I entered 5/14/2021 for Line 22. Column (c).

In fact, the error keeps popping up no matter what date I enter.

If you imported your 1099-B you need to check each transaction to find the one with the improper coding or improper date that is triggering the system.  If you can't find it because there are too many transactions I suggest deleting the 1099-B and entering summary totals and attaching the 1099-B to the return after that.
