At 6'3", I doubt the Target Schwinn is anywhere near your size. If you can make it fit you (which I doubt) getting it adjusted to work properly isn't a bad option in the short run. Another option is an old MTB from Craig's List or garage sale (probably need a 21" to 23" frame for your height) and ride the heck out of that till you drop a bit of weight and figure out what you really want to do. (I rode a $40 Craig's List MTB for 1,000 miles before moving to a road bike and it helped me decide which way to go). Good luck and keep riding. You'll be amazed how fast the weight drops if you just keep riding.
