After you file

That happened to me and my daughter as well!  Mine was changed and so was hers.  She just got her refund which was $600 lower with the explanation that it was because of line 30.  She was given a reference number and we will be following up with the IRS for clarification.  Mine is still showing pending in the IRS system, but since I see the same change made to mine on Turbo Tax I am thinking mine will be lowered as well.  So frustrating!
