I cannot find where the Information Return System makes or stores the txt files required by Oklahoma to file Oklahoma forms 1099-MISC. If this file must be created another way, please share.
Welcome to the community and thank you for posting a question. 1099 files can be sent to the state if the state participates in the Combined Federal-State Filer Program. Please see this knowledge base on how this is done:
