Thank you for your reply, COR115.

I can see it’s really useful for you to be able to delete recurring transactions in batch. However, this feature is currently not offered in QuickBooks Online.

If you've just started, I'd suggest signing up for a new QBO company using your existing log in credentials. Then, you can find an app to re-import your data which will not turn them into recurring transactions. Or, you can follow the article about converting a Quicken file into a QuickBooks Online company file. 

We're just around if you have other questions.
