Interim entry - year end processing

I need to enter some reimbursements paid by AP in to payroll for W2s.

These amounts can be entered as Interims, but they should have no taxes calculated.  I don't want to use a non taxable pay type, as the tax records record the amount as 'Excludable'.

I was successful in using the Off Cycle Interim to do this, but manually overriding the taxes will be cumbersome - there are about 200 checks to enter for this.

I tried using the Adjustment Interim, but am getting a 'Fetch from F0901 failed' error when I use any pay type but '1'.
