I also just received the CP 27 and it turns out I am eligible for a $1,502 credit! I went back into Turbotax to see where I might have made a mistake. As you saw, it only asks a question about 2019 income and then says I am not eligible. This is a huge mistake on something that should be easy for Turbotax to get right based on the personal income I entered along with my income. Please fix. I would not have known about this without a letter from the IRS telling me how to file for the credit.
