Unfortunately, these are not normal times. The IRS has had their resources burdened with the stimulus payments, meaning far fewer resources available to process tax returns.Then, there are also their own employees taking sick leave or vacation or personal leave out of fear of the new virus. On top of that, Congress has cut their budget every year for several years, so they were already stretched thin.
You do at least know your return is being processed and just have to wait for further progress. You're not alone. My own return was in processing for 4 weeks.
You could try the Tax Advocate office to see if they're taking calls.
