Plz it's URGENT

Hello,

I have a query related to TDS.

A partnership Firm deducted TDs on Contract(RS 2000) and Interest on unsecured loan(RS 48000) on 31st march2009. TDs was deposited in May month by ETDS. During Filling Challan 281 all payment of rs 50000/- credited to Sec 194C(Contract). no payment is cr to 194A (interest). now is it possible to correct it.?.

Thanks in advance.
