What is the MD property transfer tax exemption code for transfering property int

I am working on another shortsale and I went to go record the “warrantee deed to trustee” document for the land trust but Montgomery county is trying to charge me transfer taxes even though I tell them that the owners are 100% beneficial owners of the trust.

They told me that if I can show them a MD property tax exemption code that states I dont have to pay property transfer tax for my situation they will not charge me.

Please does anyone know this code?
