Hi h20kj-msn-com!

Good to see you here. Let me assist you with the 401(k) deduction.

It seems that you entered the 401(k) deduction using a journal entry. If so, it'd be best to seek some help from your accountant to correct it. This is to ensure that it won't mess up your data cause journal entry is a bit complicated.

I added this link for your reference in editing a journal entry. This includes steps on how to reverse it: Reverse or delete a journal entry. You can also follow these steps:
