Does TSA have a fee?

Excuse me, I'm just curious, does the Transportation Security Administration (TSA) charge a fee for their services? I've been flying quite frequently lately and I've noticed that there are some additional charges for certain services at the airport, so I wanted to clarify if TSA has a fee as well. I understand that the ticket price I pay for my flight includes some fees, but I'm wondering if there's a separate fee specifically for TSA's security screening process. Thank you for your help!
