Change in Amount Due

I filed my taxes in March.  I e-filed my Federal and mailed in my state (California).

 

When I did this Turbo Tax showed that I owed the Feds $3,839, and would be getting back $138 from the State.  I just logged into Turbo Tax and there were updates that down loaded.

 

When I opened my documents, Turbo Tax now shows I only owe $1,822 to the Feds and the State owes me $178.  How did this change, and what do I need to do to correct so I don't have to pay so much to the Feds.
