It does not appear to be working properly. I took out a 401k covid distribution in 2020. I opted to spread the tax burden over 3 years. I used 8915-e in 2020. Turbo tax allows me to fill in the 2020 total distribution and the amount I claimed on 2020 taxes, which was 1/3 of the total. However, it is not adding it to income and my running tax payment/refund does not change. Further indicating that it is not adding this amount to 2021 income.
