Retirement tax questions

I followed the above instructions and it appears I've entered my information correctly. I've verified my Covid distribution (1/3 of it anyways) shows up on line 5b via Tax Tools.

 

But: my taxes due did not change once I did this (I am spreading the taxes over 3 years). So either something is wrong or possibly Turbotax already transferred the information from my 2020 return?  Anybody else seeing this?
