You'll be glad to know that you have the option to integrate your PayPal and Square accounts with QuickBooks Online (QBO). This way, you don't need to manually enter your sales transactions anymore. Let me guide you how to do it.
To integrate PayPal and Square, follow these steps:
Log in to your QBO account at qbo.intuit.com.
Open a new tab and go to appscenter.intuit.com.

Re: recording bank deposit online with sales tax and fees
From banking menu, make a deposit. Line 1) enter the sale amount using a revenue account. Line 2) enter the sales tax amount and include the taxing jurisdiction in the name field. Line 3) enter the credit card charge as a negative number using a credit card fee or bank charge expense account.
Note: this method will not work if you are tracking sales by item. If you are, you need to create and invoice and mark it taxable. You then receive a payment then make a deposit. Add the credit card fee as a negative to the deposit.
