was accepted since jan 27 but no refund yet.

The IRS issues most refunds within 21 days, assuming that there is no delay and nothing is holding your return. Some returns are subject to an automatic hold due to the Path Act when certain credits are claimed. 

The (PATH Act) prevents the IRS from issuing early refunds (before mid-February) on any tax return that claims the Earned Income Tax Credit (EIC) and/or Additional Child Tax Credit. For more information click on the link below
 

When will I get my refund if I claimed the Earned Income Tax Credit or Additional Child Tax Credit?

Keep in mind that once your return is accepted for processing by the IRS and/or State we have no control over your return. You should track your refund directly from the IRS and/or Department of Revenue’s Website. These websites have the most accurate and up to date information. They get updated once a day.
