QB Issue Resolution:

the only report that will do you any good is a general ledger report for all dates

due to QBO’s limited transaction reporting you might need to report on several date periods, print or export the report to excel

you may need an accountant to log in, I have not nailed down whether a user can access the report or not, enter general or ledger in the search box at the top of the reports screen
