owners draw and vat

I have made some  personal purchases from my business bank account and trying to match them from the bank statement. 

I have the owners draw account set up and can select it in the category when viewing the personal transaction in the banking view. But in order for me to add it i need to fill the vat code box in. What do i need to put in the vat box ? 

For example i bought some camera equipment so i know it had a standard vat code 20% but i do not want this vat recorded on my vat return for the business
