Does GreenDot Bank issue federal tax refunds?

[cloner3]

I received a check from Green Dot Bank and states it is my federal tax refund. I want to be sure this is legitimate

[DoninGA]

If you requested to have the TurboTax account fees deducted from your federal tax refund, the IRS will send the refund to a third party processor to have the fees and the service charge deducted. The third party processor will deduct the TurboTax fees plus the service charge and then attempt to direct deposit the remaining refund balance into the account that you entered on your tax return.

The third party processor is Santa Barbara Tax Products Group, a wholly owned subsidiary of Green Dot Bank

If they could not direct deposit the refund successfully then they convert it to a check mailed to the address on the tax return for an extra fee.  Check your account here :
