Usually you can expect to get a refund within 21 days. 

Once your tax return has been accepted, you can check the status of your refund by using the IRS Where’s My Refund? tool (fastest option) or call the IRS at 800-829-1954. Once they have processed your return the date that your return will be deposited into your account or mailed will be shown there on the Where's My Refund tool.
