I would check over your return and see if you can see anything wrong especially in the payments section.  Make sure you agree with all the amounts listed.   Like is the difference the same or close to the refund you got last year?  Maybe you put down that you applied last year's refund to this year?  Or you applied part of your refund to next year as an estimated payment.  Or you put down you made a payment with an extension or paid an estimated payment that you didn't make?

There should be a phone number on the notice that you can call to ask about this change if the notice itself is not clear or you cannot figure it out.
