How long does it take for the irs to accept your efile

It depends.

If you e-filed your return in January, it'll stay in Pending status until the IRS processes the backlog of returns.

After January, e-filed returns generally sit in Pending status for 24-48 hours before coming back as either Accepted or Rejected. Sometimes state returns stay in Pending for several days or even longer.

The estimated 21-day period to receive a refund is calculated from the date the E-File is successfully submitted to the IRS--and not necessarily from the date it is submitted in TurboTax.
