Sorry but the IRS budgets have been reduced every year for more than a decade and the hiring freezes have been exasperated by the covid situation so anything that requires human interaction (like the PTC correction) is taking way too long to process and there is no way to speed it up especially for something that is a "one of" never to be repeated. If you want to complain do it to your congress person as they are the ones hobbling the IRS's ability to service the taxpayers timely.

As of June 10, 2022, we had 11 million unprocessed individual returns which include returns received before 2022, and new tax year 2021 returns. Of these, 1.9 million returns require error correction or other special handling, and 9.1 million are paper returns waiting to be reviewed and processed. This work does not typically require us to correspond with taxpayers but does require special handling by an IRS employee so, in these instances, it is taking the IRS more than 21 days to issue any related refund and in some cases this work could take 90 to 120 days. If a correction is made to any Recovery Rebate Credit, Child Tax Credit, Earned Income Tax Credit or Additional Child Tax Credit claimed on the return, the IRS will send taxpayers an explanation.
