Money taken from SIPP in drawdown

If you take a cash lump sum ( not the 25% tax free)from your SIPP in drawdown, which box do you fill in on the SA100 form? Do you need to put a note at the end of the form informing you the money came from a SIPP ?

Hi,

You would declare TR3 box 11 and any tax deducted at box 12. 

Thank you.
