Letter from the IRS

I had Jackson Hewitt do my 2008 taxes, all of them.  State and local were even and I have already gotten my federal return.  But today, I got a letter from the IRS.  Pure panic just seeing the letter.  My hands shook as I opened it and I’m still riding the buzz.  My return was incorrect and they’ve made an adjustment.  I’m due $382 more money.  Relief.  I wonder if they’ll direct deposit it or send a check?
