"1. I have some payments made to a credit card that I DO have in QuickBooks, but the bank account where the payments are coming from are missing. Under which account could I register these payments?"
If the payment came from the owner's personal account, you can use a bill, expense, or check transaction. List the credit card liability account as a positive amount on Line 1 and Owner's Equity/Capital (or the appropriate equity account if partnership/S-Corp) as a negative amount on Line 2. That will record the expense and a corresponding amount to the equity account.
"2. The cafeteria had an accident at one of its locations and the insurance company deposited some money with us. Under which account do I register this income?"
Assign Insurance Proceeds (other income) to the deposit.
"3. We use an app called Dripos (which is like Square) and by mistake it deposited money for product sales that corresponds to another of our locations, so we transfer it to the bank account of the corresponding location. Can I register these transfers as “Dripos Income” so that the number stays at $0?"
That works. As long as you assign the same account to the deposit and the transfer, the two transactions will net to $0.
"4. The owner transferred money from the coffee shop business account to his personal account to pay the credit card, but he made a mistake and the amount does not match. Let's say he transferred $334 and the card shows a payment of $344 (from a bank account that is not in quickbooks). How do I register these two transactions?"
That's no problem. Assign both transactions to the appropriate owner's equity account (see #1). The equity account will decrease by $334 and then increase by $344, a net increase of $10.
