I figured it out. The total on the Summary page includes estimated payments for federal and state (but not including any federal or state overpayments). If click through the various pages, can find the input amounts for federal and state overpayments. It would be great if Turbo Tax would be more specific on Summary page to state federal and state estimated payments, and even better to include a line item on the Summary page for federal and state overpayments applied from prior year to current return (which will make the input and review process easier and potentially more accurate as well). It's a bit confusing, as including federal and state info in federal section (but understand why). Thanks.
