Pretty sure my belly button is an inch+ too high. What do you think? (photos)

Thank you for your question and photos. The belly button does appear a little high. With an extended abdominoplasty the belly button is left attached to its stalk and brought out through an opening in the abdominal skin flap. Ideally, the level should be at the level of the anterior superior iliac (pelvic) spine or about 15-17cm from the upper labial comissure (where the labia majora come together). If loose weight, and the lower skin flap relaxes, one might "float" the belly button and reattach it lower to the fascia at the time of further skin excision at the pubic scar line.

A pre-op photo would be very helpful in answering your question better, as some people have higher belly buttons than others. Your belly button is left attached in its original location on the abdominal wall, but depending on its length there can be some variation as to where it is brought out on the abdominal skin.  Based on the 2 photos you provided your results look good. 

With a tummy tuck, extended or not, the belly button is left attached in its original location. The skin below that are is removed, and the skin of the upper abdomen is pulled down and stretched to cover that area, and an opening is made overlying the belly button to bring it through. Some people have naturally higher belly buttons, which may be your situation. Your results overall look great.

Maybe but you did not post before photos so we could compare the location??? Either post or seek in person opinions..

Your before pictures would have been helpful. The position of the bely button should not change with tummy tuck. I would leave it alone.

Usually the position of the belly button relative to the abdominal wall stays the same after a tummy tuck since it is left in place and the skin is pulled down over it. The new hole for it is then made where it is located. There is tremendous variation in where a normal belly button is located on the abdominal wall and although yours is high, it does not appear to me to be abnormally high. And trying to move it lower is likely to leave significant scarring. You should discuss your concerns with your plastic surgeon. Good luck to you.
