Hi @Keiko2325! Philly does I-751/N-400 combo interviews, had mine in June of last year. If you have already submitted the previous lease in your I-751 application, then it should be in your file when interviewed. Regardless, it wouldn't hurt to resubmit it through the N-400 online system application. If you guys didn't have a lease prior to December 2021, you may be asked to explain what kind of housing arrangements were made since becoming a permanent resident and provide relevant evidence.
Good luck!
