Transaction with Multiple Inputs having Same Address
Inputs do not refer to addresses, but rather unspent transaction outputs (UTXOs).  If there are multiple UTXOs payable to the same address, then a transaction spending those UTXOs will have to list them individually, and cannot lump them together into a single input.  The fact that all the UTXOs are payable to the same address doesn't matter; they still need to be listed as inputs separately.
