Had to send three Federal returns by mail (TY2022-TY2024) for a client that I was unable to e-file (MFS status, system error as we didn't have the SS# for the uncooperative spouse).

Returns were sent to Ogden, UT via Certified Mail about 7 weeks ago and have the USPS electronic receipts.

Just curious, has anyone sent in paper returns this tax season, and if so, what kind of processing times have you had?
