I'd be pleased to help share the steps on how you can import your last year's transactions in QuickBooks Online, xtqmb3w.

When linking your account for the first time, QuickBooks will automatically download your most recent or 90 days' worth of transactions.

To import the last year's statements, we can use the WebConnect feature. Below are the steps to complete the process.

Step 1: Pick a start date:

1. In QuickBooks, go to the Accounting menu and then select Chart of Accounts.
2. Look for the bank or credit card account you want to upload the transactions into.
3. Click View register.
4. Find and write down the date of the oldest transaction. Usually, the oldest transaction is the opening balance.

Step 2: Get transactions from your bank:

1. Sign in to your bank or credit card’s website.
2. Follow your bank’s instructions on how to download CSV files of your transactions to your computer. Every financial institution has different steps. For Bank of America, Chase, and Wells Fargo.
3. Check the date range for the download. It should be at least one day before the date of your oldest transaction.
4. Download your transactions. Save the file somewhere you can easily find it, like your computer's desktop.

For more details about this process, we can refer to this article (proceed to Step: 3): Manually upload transactions into QuickBooks Online. In the same write-up, you'll find links on how to set up bank rules as well as reconcile your account.
 

Once imported, I recommend editing, assigning, and categorizing your transactions. Also, you can match them to the existing entries in the software. Doing so will help you ensure the accuracy of your financial records.

I'm only a post away if you have any questions about bank-related concerns or anything else you need in QuickBooks. I'll be glad to share and provide further assistance whenever you need one. Have a wonderful day, xtqmb3w!
