Ethical dilemma at work: need guidance

Lately, I’ve been at a bit of a weird place at work. I’ve been working at a startup for the last 1 year. This is my first startup experience. It had been a pretty good experience thus far, as I’ve started doing well, the trust on me has increased, and the kind of asks have become weird. I’ve increasingly started doing founders office work, which includes helping with the MIS, build projections. As I’ve started working on this, what I’m realizing that a lot of it is hogwash. A lot of the transaction that is reported is not meaningful. Additionally, we are reporting unachievable projections, even though it is evident it won’t work out. It’s kinda on the fence, and I don’t feel like doing it. But then again, this might just be how most startups work. Have you guys faced this? If yes, what would you do in my position?
