Thank you for posting here in the Community, cezer2000. 

I'm here to guide you on how to categorize transactions in QuickBooks Desktop. Also, it would be best to consult an accountant for the appropriate accounts to use. This way, they can advise you on how to handle checks received from Social Security.

Here's how to record the deposit in QuickBooks: 

1. On the Homepage, select Record Deposits / Make Deposits.
2. In the Payments to Deposit window, select the payments you want to combine. Then select OK.
3. In the Make Deposits window, select the account you want to put the deposit into from the Deposit to dropdown.
4. Check the deposit total. Make sure the account and selected payments match the deposit slip from your bank. Use your deposit slip as a reference.
5. Enter the date you made the deposit at your bank.
6. Add a memo as needed.
7. When you're done, select Save & Close.

That should get you going in the right direction. Please don't hesitate to reach out to me again if there's anything else I can help you with. Have a good one!
