If
you e-filed your return in January, it'll stay in Pending status until the IRS
starts processing the backlog of returns.
After January, e-filed returns generally sit in Pending
status for 24-48 hours before coming back as either Acceptedor Rejected. Sometimes state returns stay in Pending for
several days or even longer.
