Over the weekend, I opened up my Turbotax program, and as often happens, the system decided to reload the whole enchilada; and I believe that this time the updated program found and transferred the 2020 tax info to the 2021 form. See if that works for you. (Of course, the proof of the pudding will be in the eating, and only when I have received all my supporting information from banks, etc. will I know for sure.
But I tend to agree with you that obvious, essential items can be overlooked by the programmers who are engineering all these revisions, and what is given today can be taken away tomorrow.
Best of luck!
