Ask HN: Need help with tax strategies

find myself paying an extraordinary amount and was wanted to ask the HN community for literature/advice on personal taxes and also a small C corp that is more of a placeholder than generating much income at this point (is generating losses)

are there worthwhile people I should reach out to? I've caught my CPA not recommended what I consider common sense things twice now and he seems to feel like he is in the right even though I increased my refund...
