Who Approved it? If the IRS is still processing it, it has not yet been Approved. (Maybe the State return was the one that was approved.)
The IRS is seriously backlogged due to all the extra stimulus filings, as well as a few million unprocessed 2019 returns left over from the COVID shutdown. Contacting the IRS will not help, and it has implored taxpayers not to call. Lots of other folks are still waiting, so please continue to be patient. Also see:
