Paper return still not showing received by IRS - filed in April, check cashed

[m06wc21]

I filed our joint taxes In April and included a $4k+ check, which was cashed not even a month after we mailed. But on the ID.Me website there is still no tax transcript for 2021. I waited until October to check because I knew it was taking a while but does anyone know why its taking so long? I dont think I made a mistake since I did it through Turbotax but I'm also wanting to make sure its all good. Anyone have any ideas?

Since your check was cashed you know they received your return. Mailed returns can take 9 months to process.
