I just started QB online 3 weeks ago.
Is there anyway to download my full year of bank transactions instead of just the last 3 months?
You can login to your bank website and download the transactions for a specific date range into an Excel csv file and then upload them directly into your bank feed to categorize, add to your bank register, and reconcile month-over-month. Make sure there are no duplicate transactions before importing the transactions into the bank feed. You may need to format the data a little before uploading it as well.
