How to show withholding passed through on a trust's final K-1 equivalent for Oklahoma Nonresident return

I have withholding from a trust's final year that only has Oklahoma oil royalties with the withholding. Can I e-file if I need to attach the K-1 showing the withholding or will Oklahoma tax agency be able to see that from the 513NR filed that has a copy of the K-1 equivalent? I cannot see anything on the Tax payment worksheet for OKLA return that is specific; only the "other state withholding" line with no place to say it is from the final year trust return.
