My employer reimbursed my professional dues, it is a taxable benefit on Releve1. In Receipt section, I am asked if I was reimbursed. Why is that, it's a taxable benefit?

My professional fee are showing as a taxable benefit on the R1 but not on the T4; can I still claim this expense on both returns? if so, how do I reported as income? Does Turbotax include it in income for Federal only by answering "Yes" to the question on the Receipt section "did your employer reimburse you for the professional due?"

Thanks
