If you rent your STR for seven days or less, you may meet the STR tax loophole, making your income non-passive as long as you materially participate. This will be reported on Schedule E. If your short term rental is rented for 30 days or less plus you provide substantial services, you will have to file as a business, reporting on Schedule C.
there is no way to move schedule E to schedule C. if proper reporting is on schedule C and no longer or never on schedule E you have to delete the schedule E and re-enter the data on schedule C..
