Xrp destination code and ledgar after setting message key for flare tokens

[jmdsmallengine]

I set the message to recieve my free flare tokens via the xrp toolkit. I am trying to send additional xrp to my nano x address to hopefully have counted into the snap shot my issue is coinbase is require a destination code in which my ledgar isnt displaying i doubke checked the xrptoolkit and found a destination code setting in which i could toggle on or off in which is currently off. So im curious as to what destination code i need to enter and or where the issuenmay be. Ive tried copying the dest code for recieving xrp on coinbase but all test transactions kicked back my xrp. Any help or suggestions greatly appreacted thanks
