sir i have to pay fee to CA the bill given by CA is

Amount (In Rs)
Fees 2,500
CGST 9% 225
SGCT 9% 225
Total 2,950/-


I have deducted TDS
Less: T.D 10% 250
and cheque issues 2700 to CA

weather my calculations is correct? that is weather i have to deduct TDS (2500x 10% =250) on Rs 2500?
because in the bill it already included GST.
