Welcome to the Community.

I'll ensure you'll be able to enter your December-21 until March-22 figure in QuickBooks Online.

Depending on your preference, there are plenty of options to enter those data. You can create a sales receipt or invoice if it's money in a transaction. Then, record it as a cheque, expense, or bill for money-out transactions.

Option 1: Create a sales receipt for money in a transaction.

1. Click the + New icon.
2. Select Sales receipt.
3. Choose the customer from the Customer dropdown. If you haven't set them up hit Add a new customer.
4. Fill in the sales info, such as the payment method and the date.
5. Enter line item for the products and services you sold and the amount.
6. Once done, click Save and close or Save and new.

Option 2: Create an invoice for money in a transaction.

1. Click the + New icon.
2. Select Invoice.
3. Choose the customer from the Customer dropdown. If you haven't set them up hit Add a new customer.
4. Fill in the sales info such as the payment method, date, quantity, and GST option if necessary.
5. Enter line item for the products and services you sold and the amount.
6. Once done, click Save and close or Save and new.

Here are the options for money-out transactions.

Option 1: Create a cheque.

1. Click + New.
2. Select Cheque.
3. Choose the Payee from the dropdown ▼.
4. From the Bank account dropdown ▼, select the account the cheque withdraws money from.
5. Complete the cheque fields you need.
6. Choose the Print optional.
7. Once done, hit Save and close or Save and new.

Option 2: Record an expense.

1. Click + New. Then select Expense.
2. In the Payee field, select the supplier.
3. Choose the account you used to pay for the expense in the Payment account field
4. In the Payment date field, enter the date for the expense.
5. In the Payment method field, select how you paid for the expense.
6. In the Category details section, enter the expense info.
7. Enter the Amount and GST if necessary.
8. Once done, hit Save and close or Save and new.

Option 3: Create a bill.

1. Click + New.
2. Select Bill.
3. From the Supplier ▼ dropdown, choose a supplier.
4. From the Terms ▼ dropdown, select the bill's terms. This is when your supplier expects to be paid.
5. Enter the Bill date, Due date, and Bill no. as they're recorded on the bill.
6. Fill in the bill details in the Category details section.
7. Enter the Amount and tax. The total amount displayed is based on the option selected in the Amounts are field.
8. Once done, hit select Save and close or Save and new.

I've also included the following articles below for more insights:

• Record invoice payments in QuickBooks Online
• Deposit payments into the Undeposited Funds account in QuickBooks Online
• Record and make bank deposits in QuickBooks Online

Also, you can connect your bank account or manually upload bank transactions and then add them from the For Review tab. These options are a bit faster since it eliminates manual entries.

For future reference, I've added this resource about reconciliation to ensure your QuickBooks balance matches your bank or credit card balance: Reconcile an account in QuickBooks Online.

You can prepare your historical transactions in XLS and utilize an importer tool.

Another option, purchase a 3rd party service to do so.
