I am the representative of my mother's estate. When I entered my information for the signature on her form, her taxes due when up $222. Why?

I am sorry for your loss.

Unfortunately we don't have enough information to help you. To figure this out one really needs to review the actual forms before entering that information and afterwards to track down what changed. It sounds surprising.  Perhaps some calculation wasn't being done until all fields were filled out. Doesn't seem right, but I'm just guessing.
