Do a water change. That is the best way to lower ammonia. I change as much of the water as possible.
What kind of fish do you have? It seems that your tank is not yet cycled, so you will need to be careful about doing water changes to make sure the fish stay healthy.

I have an elephant nose, pictus cat, albino Cory, 1 angel, upside down cat.
- I use bio-spira
- prime for dechlorinate
I have found out that the tank is not cycled so I'm unfortunately doing it with fish. Which is hard on fish
I don't want to lose anyone.....
Did 10 gallon water change (40) gal tank
Nothing changed

I would try a bigger change at least 50 percent keep doing that until your ammonia drops

You will need to do a much bigger pwc than 10g. Try more 30g. 4ppm ammo is a lot. So, you need to get that lower. Fish-in cycling can be done though. It's good that you have a test kit to help you out. What brand of test kit are you using?
Just in case, here is an article about fish-in cycling.
I just learned about cycling but I already have fish. What now?! - Aquarium Advice

My suggestion is to make two 50% PWC back to back, maybe with two hours in between..
