Hi @tracyla,
Let's go through a few things to ensure all your bank transactions in QuickBooks Online (QBO) are in the register.
The default view for a bank register is filtered through dates, in descending order. This way, the latest transaction is always on top. If you have a lot of transactions that can't fit a single page, you'll need to scroll at the very bottom. You'll find links such as Next and Last. This is how you can navigate through other pages in your bank register.
In case you have missing transactions, check your online bank's For review tab. See this article for additional steps you can take: What to do if you can’t find downloaded transactions in QuickBooks Online.
Utilize the comments section below if you have additional concerns. I'll get back to you as soon as I can.
