I am trying to set up the dental benefits deduction and have not found any information of which deduction option connects to box 45 in the T4. I also tried to set it up manually but it didn't give box 45 as an option to set it to. Has this not been set…

My starting balance is incorrect in my remittance summary. I tried to adjust the payments part so it would zero it out but it didn't clear it out. How can I get it removed or adjusted?
