When you prepared your return you were given the choice of direct deposit or a mailed check. What did you select?
Check the IRS site:
You need your filing status, your Social Security number and the exact amount (line 20a of your Form 1040) of your federal refund to track your Federal refund.

If you entered incorrect banking information for your refund, you can change it if your return is rejected. If it is accepted, however, it is too late to change it. The bank will reject the refund and send it back to the IRS. Then the IRS will issue a paper check and mail it to the address you put on your tax return. Expect a delay of at least a couple of weeks to receive your refund.
