How is TurboTax software handling those who's employers didn't withhold Social Security Tax due to executive order?

it's up to the employer to collect between January and April; it won't be on the tax return

What a bloody mess this will be if you are not still working for that employer in 2021 ...

[Opus 17]

The employer is required to withhold extra payroll taxes in equal installments between January 1 and April 30 to catch up on the deferred tax payments. This is not a situation that is covered on your income tax return.

I have not followed the news to see what would happen if you quit or retired, but I imagine it will end up being a mess.  The latest proposed stimulus package apparently does not include forgiveness of the deferred amount.

Per the news this AM the new bill will extend the payback until 12/31 ... what a bloody mess this will be for employer's who actually choose this option.
