Your post is a bit confusing, but the first thing to realize is that school requirements and immigration requirements are not the same. As mentioned above, if your DS-3025 is marked "complete" then there is a reasonable chance that you won't need anything else to satisfy USCIS.
As for the school vaccines, that is what is confusing. First, I think you mean your daughter got Td, not Tdap, since Tdap includes pertussis. Why she would have gotten just Td is a mystery. I am also confused why the pharmacist thinks it is a problem to give a Tdap dose, since the recommended interval for dose 1 to dose 2 is only 4 weeks, and dose 2 to 3 is 6 months. I went through getting K-2 kids vaxxed for school a few years ago. We just took our DS-3025 (a copy of course) and had them add the new vaccines to that so they would all be listed together. As for chicken pox, I think your choices will be getting the vaccine or getting a titer to prove immunity. Nobody should be looking at pictures to confirm chicken pox history.
