Thank You, PB7781 for the additional info.
Mine is a joint return and none of us have that unemployment. I am retired few years back and on Medicare already. This APTC (from 8962) is for my spouse, who never worked. Same situation last year (2020) as well. Given this, just for 2021 it defaults to 133% (percentage of AGI over FPL)? Wow! If it is, that will help me quite a bit. Not filed yet, but will wait for some time and as well as for the response to my token number 900296.
