Is there income limit for me to benefit from FSA contribution I made in 2022?

I made contributions (and disbursements from my FSA account) in 2022, but when I add these contributions/disbursements my return doesn't change? I thought FSA is pre-tax, and as such, should lower my taxable income? which begs the question, is my income too high for me to benefit from pre-tax FSA deductions?
