Just Bought used 2012,Turbo Manual transmission, can't get in gear, Reverse 1 and 2nd gears,

Had no problem or clue of transmission difficulties at dealership. Went home
on a 50 mile drive to my destination. Later, when starting vehicle in driveway,
slight slope, and put in reverse, shifter would not go into gear, ( yes i pushed
down on the shifter while pushing in the clutch to get into gear but absolutely
would not go in. I tried different depths of pushing the clutch, barely halfway
and fully to the floor. It was as if the clutch would not engage into the gears. so
i coasted out of the driveway, then tried to get the car into first and second,
absolutely would not go in. I waited in a non busy cul de sac, remained calm
and after minutes of gently trying it finally went into gear and i drove to a safe
area, parked it and called a tow truck to get it to a dealership.
What should I expect to hear from the dealership as a fix for this? (Of course
this all happened on a Saturday afternoon and nobody can look at it till
Monday. Any area of this problem I should look for as a heads up? Should I
expect a new transmission, or is this an easy fix, have you heard of this
before?
