Federal Tax Refund - Status changed from "Pending" to "We cannot provide..."

Hello,

 

I filed my tax returns through Turbo Tax E-filling and it was accepted on 3/15. I received my State Refund within the first week but still have not received my Federal Returns. When I checked the Refund Status page on the IRS website, it initially sends "Pending" but that message has now been changed to:

 

"We cannot provide any information about your refund. Be sure to:

  • verify your filing date;
  • check with your tax preparer or tax software provider; or
  • verify you received your electronically filed acknowledgement e-mail."

Has anyone ever experienced this and have any recommendations if I need to take any actions?
