Upper bound an integral with exponential function
@ Iosif Pinelis: I am trying to understand why we have $I_2 =O(1/n)$. Can you give me any ideas?

I think you miss the formula of the second term. It is $1-(t-a)^2$ in the denominator.

Stein's lemma for Gaussian variables proof
I have my own answer now, I choose $\alpha = \frac{\mathbb{E}\{Z_1Z_2\}}{\mathbb{E}\{Z_2^2\}}$

Stein's lemma for Gaussian variables proof
And why we can write $Z_1 = \alpha Z_2 + \tilde{Z}_1$ with $Z_2, \tilde{Z}_1$ are independent?
