After you file

You are not in trouble ... but the IRS is looking at something on your return and simply require more time.  Due to budget cuts and hiring freezes the IRS is understaffed and some things simply take more time.  Check the IRS site every couple of days to see if the return has completed the processing and watch your mail box for a letter from the IRS if they require more information.  If you do get a letter read it carefully to determine what they want then respond as directed in a timely fashion.  And most of all don't panic ... this is common and many times will resolve itself in time.
