Why am I not seeing a Premium Tax Credit? 2020

When I signed up for Covered California in June 2020 when my COBRA coverage expired, I anticipated income of about $66,000 for the year (married filing jointly, but hubby is on Medicare).  I didn't have any estimated Federal premium tax credit at that time, so none was advanced to the insurance company, but I did have a couple hundred dollars knocked off the premiums due to a California subsidy.

 

Now I'm doing my 2020 taxes, and our income is less than a third of what I had anticipated (I forgot to do a Roth IRA conversion that I had intended to do...), and after the unemployment exclusion it's only about $10,000, yet TurboTax is still saying we are not entitled to any premium tax credit.  I can't find any explanation of how this is calculated in TurboTax, they just wave their figurative hand and tell me not to worry my pretty little head about it, they'll figure it out for me.  The Covered California web site won't let me see information for 2020 eligibility, but they'll let me apply for 2021 or look at (but not change) my information from my 2020 application.  I remember last year I had seen some tables of what income levels were eligible for which benefits, but I can no longer seem to find them.

 

How can I see where/how the determination is made that I'm not eligible for a credit, and how far I am from being eligible?

 

Thanks,
