The IRS tries to get most refunds out within 21 days, however some refunds can take longer to process. If you filed on February 6, you're right at 22 days. You can check the status of your refund at the IRS Where's My Refund site to see if there's anything the IRS needs from you to finish processing your return or if they've given you a direct deposit date. If you're looking for your state tax refund, you can check the Indiana Where's My Refund site.
Keep in mind that, depending on your bank, your bank may hold the deposit for a few days after the IRS sends it.
