If I filed my taxes under the irs website and my return was accepted but turbo tax is giving me a larger refund what should I do?

I recommend that you compare the return that you prepared on the IRS website with the one you prepared in TurboTax to see where the difference is.  If TurboTax picked up something that you missed when preparing your return on the IRS website, you can Amend your return.

To preview your return in TurboTax, please follow these instructions: How do I preview my TurboTax Online return before filing?
