Hi there, @NadineG730. I can provide some insights about transactions imported inside QuickBooks Online.
The first time you connect, QuickBooks automatically downloads the maximum number of transactions available from your bank. Depending on the bank, this can give you up to a year of historical transactions and the default period when it will be sync. Most banks may only download the previous 90 days.
In this case, I suggest reaching out to your bank to download the missing transactions using Web Connect.
For more information, you may consider checking out this article: Download Bank Feed transactions in QuickBooks Desktop. This includes a detailed process on how to download transactions inside QuickBooks.
Additionally, I'll be adding these reference you can use in the future:
Feel free to let me know if you have other concerns. I'll make sure to get back to you right away. Wishing you all the best.
