Client deducted tds on gst also by mistake

Instead of deducting TDS on taxable value, client deducted 2% TDS on (Taxable Value + GST) by mistake. (Don't know how Auditors can even make such mistakes!)

Can I claim full deduction 2% of (Taxable Value + GST)

Or should I claim only 2% of Taxable Value ?

Thx
