Hello there, @garret-aldridge-.
I appreciate you for posting your first concern today. I'm glad to share with you some insights about how your bank transactions are downloaded in QuickBooks.
When you first connect your bank or credit card account in QuickBooks, some banks download the last 90 days of transactions, while others can go back as far as 24 months.
To get more of your transactions for the past 90 days, you can export your transactions from your bank in a QuickBooks Online data (QBO), CSV (comma-separated values) format.
Check out these resources with detailed steps to manually upload transactions into QBO, and format your data:
Visit and post again if you have additional concerns. I'm always around here to guide you more.
