Why does my VT state tax return say it was paid on 3/11 but I habe to wait 10-15 days to get it? Direct deposit. Why such a delay?

TurboTax doesn't have that information.  Once your state authorizes your refund, it depends on your bank. They  may have additional processing times.

Refer to the Vermont Department of Taxes Check Your Return or Refund Status for more information.
