Benduff is the Anglicization of the original Irish name "An Bhinn Dubh", The Black Peak. As with a lot of Irish place names the English version can go through a number of changes down through the years before the form accepted today comes into being.
When the Tithe Applotments for Donagh were written in 1828 Benduff due to it's small size no doubt was grouped with Gortlary and Kinnaglug :

When Griffiths Valuation was written in 1857 Benduff was incorporated into the townland of Churchland Quarters, also known as Carrowtemple, Moneyshandoney & Carrick for the purposes of the valuation. The Ordnance Survey maps used to illustrate Griffiths Valuation on the askaboutireland web site use the names Binduff, Gortlary & Keenaglog for the townlands used in the Tithe Applotments. There is also Binduff Lower, a separate, adjacent townland.
This is a map of the townlands in Donagh civil parish:

This link gives the townlands which were used for the 1901 census:

And to answer the question why Benduff isn't listed as a separate townland in either census I would guess it's a case that the townland is just too small to be considered in it's own right and was as you suspected incorporated into the larger Churchlands townland.
Hope this helps.
