After you file

If it says mailed that means they have mailed you a check. 

For information on why they are mailing you out a check instead of depositing your return see this information from 'Where's My Refund FAQs':

Q: I requested a direct deposit refund. Why are you mailing it to me as a paper check?
There are three possible reasons. They are as follows:

  • We can only deposit refunds electronically into accounts in your own name, your spouse's name or in a joint account.
  • A financial institution may reject a direct deposit.
  • We can’t deposit more than three electronic refunds into a single financial account.
