Do return to enter Lincoln residence (5)
I believe the answer is:
abode
'residence' is the definition.
(I know that residence can be written as abode)
'do return to enter lincoln' is the wordplay.
'return' says the letters should be written backwards.
'to enter' is an insertion indicator.
'lincoln' becomes 'abe' (Abraham Lincoln).
'do' reversed gives 'od'.
'od' put inside 'abe' is 'ABODE'.
(Other definitions for abode that I've seen before include "House made of adobe" , "Where one lives" , "Home or domicile" , "House, home" , "Place of residence" .)
