Get your taxes done using TurboTax

If I read what the schedule says the numbers reconcile. I do not understand why once I entered this section the return showed a reduction in the amount owed.   Basically before updating section A1 & B1 below, I owed  more. I even removed the amounts and redid it and the program handled it the same way. Both times it reduced my taxes owed by $1,094

Also what does Question A1 mean? Is it just asking if we lived in the US for at least 1/2 the year or more?  Seems like a basic question but want to be sure.
