Retirement tax questions

Yes, "QCD" on 2020 1040 line 40 and, as you can see, I get started early with my taxes. Am I correct that it is possible to see the details of updates? If so, I am not in the habit of reading them, assuming that whatever corrections have been made will automatically be applied when I open my return. Would those update details have told me to delete and re-enter my 1099-R? It's also possible that, depending when the update occurred, I had already filed my return (3/14/2021). I guess I will be reading update details going forward.
