Once your return is done on turbo tax and submitted, it is in the hands of the IRS.  It takes about 21 days before the IRS process your return.  You can check your status on the IRS website at:  https://www.irs.gov/refunds and click on where is my refund.  The turbo prepaid card takes about 7-10 business days to arrive.  So your refund will not be on there until the IRS give you a date for when your refund will be deposited.  It can take 1-5 days after you are given a deposit date, for your refund to appear on your card.
