If it's a prepaid debit card, your card website should have the direct deposit info (routing number, account number & checking/savings flag) needed to deposit your refund; if you can't access that, contact your card issuer. (Make sure your card accepts Federal tax refunds; not all do, even if they accept direct deposits from elsewhere.)
If you're ordering a new NetSpend card this year, Intuit will provide its direct deposit info to the IRS (or if necessary, Santa Barbara Tax Products Group) when you e-file.
If it's an ordinary debit card tied to your checking account, use the direct deposit info for your checking account.
