Just opening my pool and balancing water. Water is clear. Tested water: TA 21, PH 7.3, FCU 1.83, TC 1.95, CH 98, CA 47. Added baking soda to first get my TA up. TA rose to 66 but PH went to 8. I still need to get my TA up a little but PH will rise if I add more baking soda. Both will go down if I add acid. How can I get my TA up and lower PH? Historically, my PH wants to stay high.

Welcome! 
Something does not compute. Two questions for you:
1) Did you let the water circulate well before testing?
2) What test kit are you using?

How are you testing? Those numbers did not come from one of the recommended test kits.

Acid will lower the PH a lot, and lower the TA only a tiny bit.
Baking soda will raise the PH only a tiny bit, and raise TA a lot.
Each time you adjust one, the other will change by a far smaller amount, so you will get to where you want to be after a fairly small number of adjustments.

Just figured out that the bottom of th pool calculator gives you the impacts of adding different amounts of chemicals. My life just got easier. Trouble Free Pool site is great!!!!
