    Indoor pools require substantially lower CYA than outdoor pools. I think 10CYA is the recommended dosage for window light UV degradation
    FC levels that high are going to throw a false/high pH reading

    If there is a way to do things less expensively and yield a superior product I am all ears

    Indoor pools should have 20-30 CYA.

    The TA is also fine. I would only be worried if the TA were below 60 ppm... assuming the beep beep boop machine is correct.

    The chlorine generator is still on I will have them turn it off

    Should I drain some of the pool because the salt looks pretty high
    it's a Pentair Chlorine generator

    If the SWG isn't giving a high salt warning then no need to try to lower salt. Pentair IC reports high salt warning at 4500 ppm, but will continue to produce chlorine even with high salt.

    First you should retest with a reliable test kit, second you should get the pH in line, third you should ignore the TA number and instead chase pH stability which will be a certain TA number, not the other way around.

    ps I maintain the CYA on my indoor pool between 20-30 ppm, this is because the CYA turbidity test minimum reading is 20 or 30 ppm depending on which view tube you use, also with indoor pools CYA is about buffering FC not so much about UV protection
