Pending simply means that your e-filed return is on its way and that the government hasn't accepted or rejected it yet.
If you e-filed your return before February 12, it'll stay in Pending status until the IRS starts processing the backlog of returns.
Keep calm and check back
Until your state or the IRS processes your return, you may hear there's "no record found." That actually means the return's still being processed. Just check back in a few days.
