Thanks for the response! Sorry for not being clear enough.
In tax year 2020 I specified $3360 as the excluded amount on Form 2241, as this is what I contributed. I did claim an additional credit for dependent care expenses of 20% of the difference ($2640).
I spent 12k in 2020 (8k / 4k per child) and 33k in 2021 (~16k per child). Box 10 in 2021 W-2 shows $6425. Box 10 in 2020 W-2 shows $3360 (the sum is nearly $5000 x 2).
I agree regarding Mercer. The problem is that customer service is useless and everything requires internal service requests, which are often misunderstood and take multiple back-and-forth.
