Welcome Teddy, I would start off by checking the trans fluid for level, color and smell. also make sure all fuses are good since this is an electronic trans, but even with a blown fuse you should still have a forward and reverse gear.

what's the mileage on your rig and when was the last service done. any other issues or things that might have led to this over time?

if all checks out, it could also be a shifter cable come loose from the trans or column / broken cable. that would be the best outcome.

welcome aboard Cliff.
I’m thinking maybe @dbrannon79 has pretty much nailed it.
Block wheels so it can not roll.
Crawl under and look at position of shift arm on the transmixer.
Insert key in ignition and turn to run position, press hard on brake pedal, turn key to off, if it will, back under with You and now observe position of shifter.
If it has not moved, someting wrong.
