I appears from the pics that it is an insect and not a disease. If you live in Florida or California they have an insect called the Asian Psyllid and it is the vector for Citrus Greening Disease. I don't think you have CGD yet as the leaves are not unhealthy. All you can do for CGD is to destroy the plant. However, there are other insects that do that type of damage, thrips, mites, for example. For any insect other than the psyllid spray the entire tree, both sides of the leaves with a spinosad based insecticide. Spinosad will take care of most insects and caterpillars. spray about every 10 days for a month.
Please research Citrus Greening Disease and if you do have it get in touch with your state agriculture agent. He will tell you what to do.

I asked a garden place and they said to buy neem oil that has fungus, insecticide and another component. To mix 2oz with gallon water and spray it around.
I’m in Texas by the way

Neem is used best on insect eggs and insects such as the numerous scale insects we have in Texas and spider mites and as a soil drench. Its fungicidal properties are not strong. Its insectcidal properties are good but not in the same league as spinosad. Neem has its place in the garden and every gardener should have some but I am afraid that in your case it is not the thing to use although it might be of some help.

What part of Texas?

I’m in Houston Texas
Before I tried the sevin insect killer that connect to water hose and dint see any help

I will give this product a go and see how that goes with this tree.

Is this tangerine ? Still looks green and we were able to juice some, tastes good. Hopefully will turn yellow in few months

They should be yellow by December. Does the fruit peel like a tangerine and what is the size in inches of the fruit. Does the fruit have a lot of seeds?

It does peel like tangerine and has a lot of seeds inside

Only the first 4 pictures. Were there others? If it peels like a tangerine its a tangerine and since it has a lot of seeds it is not a late variety. Its probably an old variety known as Changsha. The fruit will become sweeter until it is fully ripened, probably around Christmas. The size should be around 3-4 inches in diameter when ripe. The damage to the fruit is probably external only. Looks bad but not really harmful to the fruit this late in the season.
