It looks as if it needs more light. At that height it should already have true leaves starting. Does it still have a cover over it? If so remove it. Give it more light and less heat. It appears to be growing etiolated. You could repot it (and plant it a bit deeper) but the main problem is stopping it getting any leggier. I'd take it out of that tray, which is set up for germination, and put it somewhere lighter and a little cooler.

The other seedlings are that height also, such as tomatoes and peppers. Should I do the same with those?

Agree with flora, needs more light. You could move outside during the day and bring it at night. Needs real first leaves before doing anything with them. If you are going to move them to the garden, just leave them in the jiffy pots and transplant directly into the garden.
