Ok, so i have booked a TK LHR-IST rtn in J

. I have my PNR and have looked on CMT and this gives me my TK booking number. As soon as i try to look on the TK website it doesnt recognise either of the booking numbers!
My main question is how will my ticket arrive (electronic/paper) and will i be able to check in online??
Any help appreciated.
thanks B
