If MS fails to confirm these details, TK will not credit your account. The OP needs to contact his/her local MS office and get them to confirm the flight details with TK M&S.
This is where it gets complicated. I am based in Latvia, bought ticket out of Germany to Thailand from Finnish travel agency. Egyptair is not present in Latvia at all. No local travel agency can even issue a ticket out of MS stock.
I could potentially email both of them. I will maybe try to claim miles somewhere else...
