I received a withdrawal from my employer's 401(k) plan. The 1099-R included the entire amount, but at least 1/2 was from employer contributions. How do I exclude part?

My Michigan return is including the entire 401(k) distribution. Can I exclude part based on the employer contribution?

Sorry you can't ... that is taxable to you too.  That is how  401K  taxation works.
