I have the same issue as @rgrthumb - the W2 from my former employer is for imputed income for COGLI (cost of group life insurance over 50k). The W2 includes social security and medicare wages in boxes 3 and 5, but no tax withheld in boxes 4 or 6. As I am retired, the employer has no wages to withhold taxes from - the W2 is just reporting the taxable cost of group life insurance.
This new behavior of TurboTax is due to the tax payment deferral per Notice 2020-65 (see links in earlier posts about this). Turbo tax is assuming that any W2 with nothing in boxes 4 or 6 is due to deferred social security payments per Notice 2020-65. But that is not our situation.
If we are required to pay the social security and medicare tax on this imputed income with our 1040, turbo tax should provide a way to do it. If not required, or not done via 1040, TT should provide correct guidance.
