2022 Tax Return Paper Filed in 2026

So a paycheck withholding error from a job I started last October resulted in me discovering that I was actually entitled to a pretty big refund for tax year 2022. I used FreeTaxUSA to fill everything out, printed both federal and state returns and mailed them back in mid-February. I had already received the state (NY) refund I was supposed to get. Now, it's been 2 months and I still haven't gotten any news of the 2022 return I mailed to the IRS. I called this week and they said the system still doesn't have any record of it. I know that it's been received because I used certified mail. Tomorrow marks 8 weeks since they received it. They said if I don't hear anything after the 15th of May or within 30 days, I might have to mail one again. So, how long does it take for paper mailed returns from 2022 to be processed? I can't check the status online because 2022 is no longer available.
