Dichlor is acidic and will lower your pH. Plus, your FC is still too high to add more chlorine right now. Hold off on the dichlor until your FC drops to 3-4ppm.

Personally, since you don't have high pH nor high CH, I wouldn't worry about the TA. It's not all that high really. Go ahead and just add a little 20 Mule Team Borax (laundry aisle at Walmart) and use that to bring your pH up some. Start with a half a box added slowly to the skimmer while the pump is running, breaking up any clumps. Aim for mid 7s on pH.
