I am purchasing the goods with one of my supplier, who is charging the TCS@1% on the invoice. so how can i enter into thos tcs values in my purchase billing?

Thanks for reaching out to us, mohan-yprk.

Currently, TCS isn't supported in QuickBooks Online but I have a workaround I'd like to share.

We can manually track it by creating a custom tax rate. Please follow these steps:

1. Go to Taxes and click the Add tax button. 
2. Choose Tax rate, then enter a tax name and description.
3. Select the agency for the tax rate and check the Purchases box. 
4. Enter a rate, then choose the account where you want to map it. 
5. Click Save. 

Once done, you can assign it to the goods you purchased. Here's how:

1. From the Sales/Invoicing menu, choose Products and Services.
2. Find the goods/products, then click Edit.
3. Make sure to check the Purchasing information box.
4. Under the Purchase tax drop-down, choose the custom rate you created. 
5. Click Save and close.

In addition, I suggest consulting your accountant to see if they have a different way of handling TCS to make sure you're compliant with the TCS regulations.
