Contribution from home deposited (5)
I believe the answer is:
input
'contribution' is the definition.
(I've seen this before)
'home deposited' is the wordplay.
'home' becomes 'in' ('he's home' can mean 'he's in').
'deposited' becomes 'put' (I've seen this in other clues).
'in'+'put'='INPUT'
'from' acts as a link.
(Other definitions for input that I've seen before include "Data etc supplied to computer" , "Data supplied to computer system" , "Provision of data" , "Data entry" , "Signal supplied to a device" .)
