How do I deduct 1099-R by CRDP 100% P&T amount?

I claimed the exemption status through DFAS and updated them with the correct CRDP amount which DFAS Retired pay did not update the amount in the general section. However, they exempted the tax withholding and reported taxable income. This amount is reduced by the CRDP amount if I understand correctly and attach the VA compensation letter along with the exception policy for supporting documentation when filing taxes. So, the amount entered in my case would be 0 as my CRDP is more than my Retired pay?
