Your TA is 100% wrong!! Man, I hate it when they give out bad info!!! One big reason I tell people to book their own trips. Anyway....if a TA booked your stay, then that TA is going to have to call and get DME added to the reservation.On the old site it was very easy to add the info after you booked your flights...I have done it many times. Now I cannot figure it out. I did book through a TA this trip, and she said I needed to wait until 45 days out to add the ME info. I don't know if this is new, or if this is a policy of my TA and she needs to add it. I figured I would worry about it when the time got closer.
