there's a box somewhere to check if you are a real estate professional if you meet the tests. being a REP does not change how your short-term rental should be reported.
you have not provided sufficient info but it is possible that by providing significant services, the rental should be reported on Schedule C and not Schedule E
If you participate in operating vacation rentals or short-term rentals by providing substantial services it will be classified as a business and you need to report that on Schedule C whereas if your participation is minimal and you offer no substantial services you will report it on Schedule E.
The tax implications of rental income will vary depending on the length of time you rented out your property and to what extent you participated in the day-to-day management of the activity.
The decision whether to opt for Schedule C for rental property or Schedule E depends on a lot of factors. Seek advice from a tax professional to understand how rental income is taxed and ensure you go with the schedule that is legitimate
here are links to other threads about schedule C or E
as you can see this is a complex topic for which you should consult with a tax pro.
