How long does it take to process. Still showing processing after accepted since 27th

Did you claim the earned income or child tax credit? Taxpayers who claim the Earned Income Tax Credit (EITC) or the Additional Child Tax Credit (ACTC) will experience a processing delay. The IRS has just begun to process these returns. There's no way of knowing exactly when the IRS will update in any situation. You will need to keep checking the Where’s My Federal Refund? tool for updates. Updates are made daily, usually overnight.
