I got a W-2C from my employer, where I paid about $2,000 more in Social Security; however, my amended federal refund is not changed from the original. Is that wrong?

Due to the Social Security tax deferral from the CAREs act, I ended up paying about $2k more in SS taxes (came out of paychecks in 2021). However, my amended tax return in TurboTax has $0 change in federal refund (or what is owed). That doesn't seem correct, so I want to know if I'm doing something wrong.
