QB Issue Resolution:

+ Tools Restore from recent cloud backup.

 

April Fools! QBO does not provide backup restore.

 

But seriously- how back to TransactionPro and buy the Transaction Deleter which is probably not included in the importer

 

Or if you imported only as far as bank feeds would- to For Review- then you could exclude them
