Then the sale is reported on the 1065 Partnership return. That's the only way to show property depreciation recapture and take suspended losses if any. Each partner's share of any gains/losses will be reflected on each of your K-1's.
Also note that if this is for a 2021 partnership return, your partnership return is late, as it was due March 15th. If an extension was filed, then it was due Sept 15th. The late filing penalty is $205 per month, per partner. So you may be looking at some hefty late fees.
