deduction u/s 80C

Regarding 80C school fees.

Date Showing on Receipt = 30/03/2016.

but cheque cleared from bank  = 03/04/2016.

so that person did not claim deduction in year 2015-16 because he thought that deduction of school fees is allowed only on Payment basis. (i.e. cheque cleared after 31/03/2016)

so now in 2016-17 what he can do?

I have tried first by myself to find a convincing answer but nothing conclusive is  found.

so hoping for solution.. thanks in advance
