Whether GST RCM is applicable on Selling commission paid to a unregister vendor.

I mistakenly claimed ITC on the Car Tyre in GSTR 3B, and now I want to reverse it. In which column of GSTR 3B is it to appear?
Tyre cost is to be included in home delivery expenses and only ITC is to be reversed.

Whether we can do centarlized billing in gst if branches located in differnet states and want to do billing from onlY one state where head office is situated (GST number is taken only for that head office )

Hello Sir,
I am a GST Registered Trader of Fly Ash. We Purchase our Raw from UNregistered small URP vendors and sell that to the registered persons.
My question is whether I have to pay Tax on reverse Charge Although I am paying total tax on outward supplies.
According to the provision only notified goods or services are mandatory to show purchase under reverse charge under section 9(3) and 9(4) and buying fly ash from an unregistered person is not listed there.

How to deal with URP purchase for Invoice making , E - way Bill generation, accounting and GST Return. Kindly suggest me in this regards.
Thanking you,
