I have same problem and just got rejected for my first e-file.
I manually add the 8881 from(as I had no way to get 8881), and part II has 500 credit, part I is empty.
I checked my efile file, there is no 8881 form in my tax return(has 3800, 8880 etc forms), I guess that's why it is rejected.
So how can I includ the manually added 8881 in the efile?
Thanks!
