If the property was classified as a rental for the entire year *and* you did not live in it for one single day as your primary residence, 2nd home, vacation rental or any other type of "personal pleasure" use, it changes nothing to report it as rented "the whole year". Vacant periods between renters changes nothing. Personal use days "does" change things.
As for the fact you didn't try to rent it during the pandemic, it was still classified as a rental. The pandemic period does not (should not) count against you. I assume you did get it rented again as some point, and probably have a renter in it right now.
