I'm trying to get rid of old accounts receivable from previous years (2017-2019) that were entered while using Desktop (we weren't entering everything then, mostly just invoices and some payments received, etc..). We now use QuickBooks Online (since 1/2020) and the old invoices, transactions, etc.. follow us relentlessly and mess up our current books, which we have been entering religiously since start of 2020, for the sole purpose of accurate taxes. We are dealing with constant inaccurate totals, reports, etc... I've tried to find solutions to this but haven't yet found any that have helped. Thanks for any guidance you can provide!
