@emansion11 before getting to deep into any board level components, I suggest that you change the charging port ribbon cable from your sub_board to the main board. Check the connectors for any corrosion as well.

There's anyway to check the battery if it is good I change the USB port twice already then I change the battery and it still not taking the charge
@emansion11 you would need to have an ammeter and apply a load to the battery to see how many amps it can deliver. Not something that most people have laying around. you can measure the voltage while teh battery is connected but the device is off and see how many volts the battery shows on the connector. Then turn it on and see if the voltage drops. It is not a very reliable test but may give you an idea. It might just be easier to replace the battery once more.

If possible, can you check if it is charging when using a wireless charger (example only)
If you haven't got one hopefully you know someone that has a compatible wireless charger that you could borrow for a short while.
The two charge circuits i.e. cable and wireless, are slightly different although some components are the same.
At least if it also doesn't charge this way you're closer to finding out why not.
Has the phone been dropped or gotten wet at all?
Also please confirm the model number of the phone SM-N985 or N986?

لدي نفس المشكلة علما اني استبدلت البطارية. عند توصيل الشحن يشحن مدة ثلاثين ثانية ثم يتوقف. أيضا الشاحن اللاسلكي لاحظت انه يصدر صوت عند وضعه للشحن. هل يوجد حل لذلك؟

Can't find the troubleshooting guide for your model if it a Note 20 Ultra, but here's the Note 20 troubleshooting guide that may help as hopefully for the charging circuit may be the same.
Go to p.33 & p.34 to view the Normal and Wireless troubleshooting flowcharts respectively, to see if they help to find the problem. There is a common component used in both flowcharts i.e. U7002 so use the search function in your browser to locate the component in the board layout diagrams. You will have to zoom in a lot to see it.

@emansion11 Is yours a SM-N985 or N986 (5G)?
