Get your taxes done using TurboTax

I started Turbo Tax filing jointly, entered my W-2 and my federal refund was over $2,700.  After entering my wife's W-2, our refund went down to $680.  After removing her W-2 and trying to file separately, it stayed at that amount.  I removed both W-2 forms, then tried starting over and doing this separately and now after entering my W-2, it stays at $680.  Something isn't right because it looks exactly as it did when first getting a refund of over $2,700. @Howard1948
