Hello ocularhealthcent,
Welcome to the Community. I'll be happy to guide you in the right direction so you can accomplish your QuickBooks goals with ease.
The ability to edit the transactions in bulk is only available when using QuickBooks Online Advanced. In case you have access to this version, please check out this article: : Reclassify or move multiple transactions in QuickBooks Online Accountant and Advanced. Otherwise, I recommend looking into third-party apps that can assist you in bulk editing the transactions. These apps are offered on our site www.apps.com The other option would be deleting the transactions in questions and re-uploading them using the correct date.
Let me know if this info helps. I'll be a message away in case you need anything else.
