Wow, that is super broken. I agree with you that no entries anywhere produce the ideal presentation. 

The OTC will totally accept and process a paper-filed 512-S, without any issues or repercussions. I usually put in a sheet with an explanation of why the return couldn't be e-filed, but it's not technically required.

If it were me, I'd try doing the state K-1 overrides using the Royalty Withholding field, and attach a copy of the 500-B to the Oklahoma e-file, in addition to making the 49.044 entries, and figuring the OTC will figure it out. Worst case scenario, you email the OTC practitioner email address in response to a notice, explain what you did, and ask them to fix it on their end. The OTC does a good job of handling email inquiries.
