K1 trust in our 401K account -- is that taxable?

We have K-1 trusts that are in our 401K account.  Is that income taxable?

If the retirement account was issued a K-1 for the investments it holds, that does not get reported anywhere on your return.

You only have to be concerned with when you put money in the retirement account and when you take money out of the retirement account.
