Hello bosspaintingyyc-,
I hope you are having an awesome weekend! If you are trying to locate 2019 invoices under Sales-Invoices you will not be able to see them here as this area is reserved for the last 365 days of invoices.
If we want to see older invoices we can try going into our customers transaction list and we can use our filer to set the proper date range and they should be populating under the Transaction List tab in your customers profile.
I hope this information helps! I'll put a link to helpful QuickBooks Online reports that might come in handy for this one as well.
