Thank you AmyC.
I was able to find a way to update the adjustment...
When I tried to update the education expenses directly on form 8863 line 10, TT asked me to update it in student info worksheet. In this worksheet, Part X is about bond information. Since I already provided the information when I added I-Bond interest under 1099-INT, I was expecting that TT will pick up data from there but student worksheet Part X was empty. Once I added the bond proceeds in Part X, TT auto filled rest of the information which was then reflected in form 8843. So, I think this is what I needed to do. Let me know what you think.
