differance in what irs says refund should be and whaIt I received .

James,

Please refer to the following, specifically - the first paragraph. You may also find answers/help on other topics listed in this helpful document from the IRS:

https://www.irs.gov/refunds/tax-season-refund-frequently-asked-questions 

only the IRS can tell you (maybe). you should receive a notification in 2 to 3 weeks. this assumes you did not get an advance, or select to pay TurboTax fees through your refund
