The deed is mentioned in the text Madhava gave:
>There is a deed in Bengali written in 1785 A.D. (1202 Bengali year), stating that the land granted to Tota Ramdasa babaji for the service of the Deity of Sri Caitanya Mahaprabhu should be exempt from tax.
My Bengali is poor, but the original text of the deed (given in the Gaudiya-vaisnava-jivana, part II, p. 135) does not seem to say anything else than what is summarised above. Or perhaps one thing: he is adressed as Totarama Dasa Vairagi, not Babaji. Perhaps the term Babaji was too familiar for such an official document, or whas it not yet used? The importance of the deed seems to be that it gives a date for him - no other dates are given in the GVJ. Nothing mentioned of Jagannatha Dasa Babaji either.
All of this makes me wonder whether such official deeds have been sufficiently studied. They could provide historians with much important information regarding the growth and spread of Vaisnavism, and fill in some chronological gaps.
