"handling finances for household is not household help. Household help is cleaning etc, not bookkeeping"

No one here has stated the actual tasks.

The point here is that the trustee has done this wrong. The Trust isn't the employer of the DIL. The trustee can be paid a fee. The DIL is helping at the home of the beneficiary, so that is not trust-related. It is personal services in the home. The mom is not running a business, so there is nothing other than personal, whether that is help paying bills, scheduling, keeping track, whatever.

It answers the question as to why the Trust has no payroll, but not why they put the Trust EIN on the payroll. There is a mix of things here that would be examined and corrected. And now it's been clarified and answers:

"I don't see a place to enter wages (this are no Sch H wages) so would I just put them on the Fiduciary Fee line along with payroll taxes that were paid by the trust? I can't seem to find anything in the instructions."

Nope. That doesn't seem to be what's going on here.
