no way to know for sure. but consider that the IRS was not processing paper returns for about two months. in addition, it's still working on getting stimulus checks and I'll bet the staffing is not up to normal during tax season.
from the IRS website
Processing Delays for Paper Tax Returns
We continue to process electronic and paper tax returns, issue refunds, and accept payments. We’re experiencing delays in processing paper tax returns due to limited staffing. If you already filed a paper return, we will process it in the order we received it.
Do not file a second tax return or call the IRS
