Would an SSA Benefit credit of $500 be considered a Protected Amount if a bank customer has had a negative balance (NSF -$800) in their account for 20-days?

In other words, a bank customer is NSF - $800 and has not made any attempts to pay down the negative balance and subsequently an SSA Benefit Credit for $500 comes into the account; can the bank use the SSA credit to draw down the negative balance or is the customer entitled to receive the entire $500 regardless as to whether they owe the bank $800.

Or are Protected Amounts only relevant to Tax Levy's and Child Support Liens (upon notification)?

Thank you ....very interesting case.
