If you have thousands of product than it will take time to process the CSV

it is already 24hr+ but still no product have updated and tax is not enabled. I have to do it manually

You need to connect with Shopify Support so they can flush your account. Remember that

Your product CSV can’t exceed 15 MB. If you get an error when trying to upload a new CSV file, then verify that it doesn’t exceed the size limit. and as per my experience you must have less than 8k to 9k number of lines in CSV

I have 29,340 lines

Then Split the CSV (not more than 8k lines). and upload the csv again. Hope this help
