Missing 'Savings Balances' file in Numbers after iOS 26 update

I updated to IOS 26 when it became available Since the update I have not been able to find a file titled "Savings Balances" that was saved in the Numbers application. I have done a search of the computer to the best of my ability but I can not find the file. Any help would be appreciated.
