I went to LHDN to ask on this, according to the officer as long as you show proof this is your CPF money there is no issues as this is earned income already taxed in Singapore.
I also asked bank, the bank staff told me she handled many of such CPF TT when the fund come in you only need to go to bank to sign acknowledgment this is your CPF money there will be no issues.
This is what i find out and decided, make own decision ya.
