I had to dig up and replace a section of flexible PVC return line that had collapsed and pinched on top a rigid line. Hole is about 2'x2' and 18" deep. Should I just toss the dirt back in there or is sand or pea gravel better?

NO DIRT! It settles. Sand or gravel are fairly acceptable but #57 rock is better......no settling.

#57 rock is washed gravel with pieces ranging from 3/4" down to about 1/4".....I think. put it all around the pipe and you will be good to go.
